Summary The New Zealand biological control programme against ragwort, Senecio jacobeae L., began in the 1920s, and four biological control insects have been released. The ragwort flea beetle, Longitarsus jacobaeae (Waterhouse) (Coleoptera, Chrysomelidae), was introduced from Oregon into the field in 1983. The beetle has established and has had a major impact on ragwort plant populations in many areas of New Zealand, but not on the West Coast of the South Island. Field studies looked at sites where the beetle had established to determine why it had not reduced ragwort populations. The abundance of ragwort plants (13/m 2 ) and of flea beetles (three per rosette) was recorded at five sites. The biology of flea beetles and ragwort plants at each site were also recorded and rainfall data were collected. The inability of the ragwort flea beetle to reduce ragwort populations in some areas in New Zealand may be due to the high density and rapid growth of ragwort plants, possibly due to higher rainfall, and this may also have a negative effect on flea beetle populations. Numbers of flea beetles per plant was lower on the West Coast (four per rosette) than East Coast sites (ten per rosette). The density of ragwort plants was higher on the West Coast (13/m 2 ) than the East Coast (4/m 2

Mediterranean sage, Salvia aethiopis L., is a serious naturalized invasive plant of rangelands in the sagebrush steppe in the Pacific Northwest area of the United States. Two species of weevils, Phrydiuchus tau Warner and Phrydiuchus. spilmani Warner, were introduced from Europe as classical biological control agents. Only P. tau established and was widely redistributed throughout the region. Our observations show that, after the establishment and population increase of the weevil, densities of Mediterranean sage decreased at three of the four initial release sites and subsequently at 17 of 25 weevil release sites where plant densities dropped 2–5 orders of magnitude from >1/m2. Level of control appears to be associated with a combination of plant community type, disturbance and grazing intensity. The decline in weed density was most apparent in the sagebrush steppe community with light to no grazing. In comparison, salt desert scrub, annual grass dominated and heavily grazed communities showed little change in Mediterranean sage density over 25 years. This is the first report of successful biological control against Mediterranean sage.

Surveys were conducted between 1982 and 1995 on banana poka, Passiflora mollissima Bailey (also known as P. tarminiana, subgenus Tacsonia) and related species in the Andes Mountains of South America. The objective was to identify potential biocontrol agents for control of banana poka in Hawaii, USA. Host-related insect diversity was greatest in Colombia, Ecuador, Peru and Venezuela, and poorest in Bolivia and Chile. Insect species observed represented eight orders, 35 families and approximately 67 species. Fifteen species were evaluated as potential biocontrol agents, of which five received in-depth testing. Two moths, Cyanotrica necyria Felder and Rogenhofer (Lepidoptera; Notodontidae) and Pyrausta perelegans Hampson (Lepidoptera; Pyralidae), were approved and released in Hawaii in 1988 and 1991, respectively; however, C. necyria did not establish and Pyr. perelegans established but has had negligible impact. A third moth, Josia fluonia Druce, J. ligata group (Lepidoptera; Notodontidae), had been approved for release and two flies, Dasiops caustonae Norrbom and McAlpine (Diptera; Lonchaeidae) and Zapriothrica nr. salebrosa Wheeler (Diptera; Drosophilidae), were undergoing final evaluation when the programme was terminated. A pathogen, Septoria passiflorae Syd., was released in 1996, with mixed results. Banana poka remains a serious weed pest in Hawaii.

Skeletonweed, Chondrilla juncea L. is an important invasive weed in the USA, Australia, and Argentina. With the aim of finding new potential agents for biological control of this weed, surveys were carried out in 2004 to 2005 in its native range in Southern Russia and Kazakhstan, where the bronze skeleton weed root borer, Sphenoptera foveola (Gebler) (Coleoptera: Buprestidae) was repeatedly collected from different Chondrilla species. According to the literature and our survey, this buprestid is widely distributed in sandy deserts of Southern Russia and Kazakhstan. Locally, it could be rather abundant. Observations suggest that both larvae and adults of S. foveola feed exclusively on plants of the genus Chondrilla. Adults feed on green stems, larvae feed externally (within latex case) on roots and, at high population density, can cause significant damage to attacked plants. We conclude that S. foveola should be considered as a potential agent for biological control of skeleton weed, although further studies (particularly, host-specificity tests) are necessary to prove this hypothesis. Sphenoptera (Deudora) clarescens Kerremans, another sphenopteran species attacking Chondrilla in Iran and Turkey, may have a different root-feeding strategy and invites further investigations to evaluate it as a potential agent for biological control of skeleton weed.

We present the stellar calibrator sample and the conversion from instrumental to physical units for the 24 micron channel of the Multiband Imaging Photometer for Spitzer (MIPS). The primary calibrators are A stars, and the calibration factor based on those stars is 4.54*10^{-2} MJy sr^{-1} (DN/s)^{-1}, with a nominal uncertainty of 2%. We discuss the data-reduction procedures required to attain this accuracy; without these procdures, the calibration factor obtained using the automated pipeline at the Spitzer Science Center is 1.6% +/- 0.6% lower. We extend this work to predict 24 micron flux densities for a sample of 238 stars which covers a larger range of flux densities and spectral types. We present a total of 348 measurements of 141 stars at 24 micron. This sample covers a factor of ~460 in 24 micron flux density, from 8.6 mJy up to 4.0 Jy. We show that the calibration is linear over that range with respect to target flux and background level. The calibration is based on observations made using 3-second exposures; a preliminary analysis shows that the calibration factor may be 1% and 2% lower for 10- and 30-second exposures, respectively. We also demonstrate that the calibration is very stable: over the course of the mission, repeated measurements of our routine calibrator, HD 159330, show a root-mean-square scatter of only 0.4%. Finally, we show that the point spread function (PSF) is well measured and allows us to calibrate extended sources accurately; Infrared Astronomy Satellite (IRAS) and MIPS measurements of a sample of nearby galaxies are identical within the uncertainties., Comment: 33 pages, 10 figures, to be published in PASP

We report the results of several studies of the {lambda}{sub c}{sup +}{pi}{sup +}{pi}{sup -}X final state in continuum e{sup +}e{sup -} annihilation data collected by the Belle detector. An analysis of angular distributions in {lambda}{sub c}(2880){sup +}{yields}{sigma}{sub c}(2455){sup 0,++}{pi}{sup +,-} decays strongly favors a {lambda}{sub c}(2880){sup +} spin assignment of (5/2) over (3/2) or (1/2). We find evidence for {lambda}{sub c}(2880){sup +}{yields}{sigma}{sub c}(2520){sup 0,++}{pi}{sup +,-} decay and measure the ratio of {lambda}{sub c}(2880){sup +} partial widths {gamma}({sigma}{sub c}(2520){pi})/{gamma}({sigma}{sub c}(2455){pi})=0.225{+-}0.062{+-}0.= 025. This value favors the {lambda}{sub c}(2880){sup +} spin-parity assignment of (5/2){sup +} over (5/2){sup -}. We also report the first observation of {lambda}{sub c}(2940){sup +}{yields}{sigma}{sub c}(2455){sup 0,++}{pi}{sup +,-} decay and measure {lambda}{sub c}(2880){sup +} and {lambda}{sub c}(2940){sup +} mass and width parameters. These studies are based on a 553 fb{sup -1} data sample collected at or near the {upsilon}(4S) resonance at the KEKB collider.

We examine the infrared properties of five low surface brightness galaxies (LSBGs) and compare them with related but higher surface brightness galaxies, using Spitzer Space Telescope images and spectra. All the LSBGs are detected in the 3.6 and 4.5um bands, representing the stellar population. All but one are detected at 5.8 and 8.0um, revealing emission from hot dust and aromatic molecules, though many are faint or point-like at these wavelengths. Detections of LSBGs at the far-infrared wavelengths, 24, 70, and 160um, are varied in morphology and brightness, with only two detections at 160um, resulting in highly varied spectral energy distributions. Consistent with previous expectations for these galaxies, we find that detectable dust components exist for only some LSBGs, with the strength of dust emission dependent on the existence of bright star forming regions. However, the far-infrared emission may be relatively weak compared with normal star-forming galaxies., 20 pages, 8 figures, accepted to ApJ

We report the first observation of a charmoniumlike state recoiling from the $J/\ensuremath{\psi}$ in the inclusive process ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}J/\ensuremath{\psi}+\mathrm{\text{anything}}$ at a mass of $(3.943\ifmmode\pm\else\textpm\fi{}0.006\ifmmode\pm\else\textpm\fi{}0.006)\text{ }\text{ }\mathrm{GeV}/{c}^{2}$. We also observe the decay of this state into ${D}^{*}\overline{D}$ and determine its intrinsic width to be less than $52\text{ }\text{ }\mathrm{MeV}/{c}^{2}$ at the 90% C.L. These results are obtained from a $357\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ data sample collected with the Belle detector near the $\ensuremath{\Upsilon}(4S)$ resonance, at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider.

Nonindigenous invasive plants pose a major threat to natural communities worldwide. Biological control of weeds via selected introduction of their natural enemies can affect control over large spatial areas but also risk nontarget effects. To maximize effectiveness while minimizing risk, weed biocontrol programs should introduce the minimum number of host-specific natural enemies necessary to control an invasive nonindigenous plant. We used elasticity analysis of a matrix model to help inform biocontrol agent selection for garlic mustard (Alliaria petiolata (M. Bieb.) Cavara and Grande). The Eurasian biennial A. petiolata is considered one of the most problematic invaders of temperate forests in North America. Four weevil species in the genus Ceutorhynchus (Coleoptera: Curculionidae) are currently considered potential biocontrol agents. These species attack rosettes (C. scrobicollis), stems (C. roberti, C. alliariae), and seeds (C. constrictus) of A. petiolata. Elasticity analyses using A. petiolata demographic parameters from North America indicated that changes in the rosette-to-flowering-plant transition and changes in fecundity consistently had the greatest impact on population growth rate. These results suggest that attack by the rosette-feeder C. scrobicollis, which reduces overwintering survival, and seed or stem feeders that reduce seed output should be particularly effective. Model outcomes differed greatly as A. petiolata demographic parameters were varied within ranges observed in North America, indicating that successful control of A. petiolata populations may occur under some, but not all, conditions. Using these a priori analyses we predict: (1) rosette mortality and reduction of seed output will be the most important factors determining A. petiolata demography; (2) the root-crown feeder C. scrobicollis will have the most significant impact on A. petiolata demography; (3) releases of single control agents are unlikely to control A. petiolata across its full range of demographic variability; (4) combinations of agents that simultaneously reduce rosette survival and seed production will be required to suppress the most vigorous A. petiolata populations. These predictions can be tested using established long-term monitoring sites coupled with a designed release program. If demographic models can successfully predict biocontrol agent impact on invasive plant populations, a continued dialogue and collaboration between empirical and theoretical approaches may be the key to the development of successful biocontrol tactics for plant invaders in the future.

We investigate the energy sources of the infrared (IR) emission and their relation to the radio continuum emission at various spatial scales within the Scd galaxy M33. We use the wavelet transform to analyze IR data at the Spitzer wavelengths of 24, 70, and 160$\mu$m, as well as recent radio continuum data at 3.6cm and 20cm. An H$\alpha$ map serves as a tracer of the star forming regions and as an indicator of the thermal radio emission. We find that the dominant scale of the 70$\mu$m emission is larger than that of the 24$\mu$m emission, while the 160$\mu$m emission shows a smooth wavelet spectrum. The radio and H$\alpha$ maps are well correlated with all 3 MIPS maps, although their correlations with the 160$\mu$m map are weaker. After subtracting the bright HII regions, the 24 and 70$\mu$m maps show weaker correlations with the 20cm map than with the 3.6cm map at most scales. We also find a strong correlation between the 3.6cm and H$\alpha$ emission at all scales. Comparing the results with and without the bright HII regions, we conclude that the IR emission is influenced by young, massive stars increasingly with decreasing wavelength from 160 to 24$\mu$m. The radio-IR correlations indicate that the warm dust-thermal radio correlation is stronger than the cold dust-nonthermal radio correlation at scales smaller than 4kpc. A perfect 3.6cm-H$\alpha$ correlation implies that extinction has no significant effect on H$\alpha$ emitting structures., Comment: 15 pages, 10 figures, accepted for publication in the Astronomy and Astrophysics Journal

We study the infrared (IR) properties of galaxies in the cluster MS 1054-03 at z=0.83 by combining MIPS 24 micron data with spectra of more than 400 galaxies and a very deep K-band selected catalog. 19 IR cluster members are selected spectroscopically, and an additional 15 are selected by their photometric redshifts. We derive the IR luminosity function of the cluster and find strong evolution compared to the similar-mass Coma cluster. The best fitting Schechter function gives L*_{IR}=11.49 +0.30/-0.29 L_sun with a fixed faint end slope, about one order of magnitude larger than that in Coma. The rate of evolution of the IR luminosity from Coma to MS 1054-03 is consistent with that found in field galaxies, and it suggests that some internal mechanism, e.g., the consumption of the gas fuel, is responsible for the general decline of the cosmic star formation rate (SFR) in different environments. The mass-normalized integrated SFR within 0.5R_200 in MS 1054-03 also shows evolution compared with other rich clusters at lower redshifts, but the trend is less conclusive if the mass selection effect is considered. A nonnegligible fraction (13%) of cluster members, are forming stars actively and the overdensity of IR galaxies is about 20 compared to the field. It is unlikely that clusters only passively accrete star forming galaxies from the surrounding fields and have their star formation quenched quickly afterward; instead, many cluster galaxies still have large amounts of gas, and their star formation may be enhanced by the interaction with the cluster., Comment: 49 pages, 9 figures, accepted by ApJ

We present the first evidence of the decay B-→τ-ντ, using 414fb-1 of data collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. Events are tagged by fully reconstructing one of the B mesons in hadronic modes. We detect the signal with a significance of 3.5 standard deviations including systematics and measure the branching fraction to be B(B-→τ-ντ)=(1.79-0.49+0.56(stat) -0.51+0.46(syst))×10-4. This implies that fB=0.229-0.031+0.036(stat)-0. 037+0.034(syst)GeV and is the first direct measurement of this quantity. © 2006 The American Physical Society.

We report the first measurement of the forward-backward asymmetry and the ratios of Wilson coefficients A{sub 9}/A{sub 7} and A{sub 10}/A{sub 7} in B{yields}K{sup *}l{sup +}l{sup -}, where l represents an electron or a muon. We find evidence for the forward-backward asymmetry with a significance of 3.4{sigma}. The results are obtained from a data sample containing 386x10{sup 6} BB pairs that were collected on the {upsilon}(4S) resonance with the Belle detector at the KEKB asymmetric-energy e{sup +}e{sup -} collider.

We report the observation of the flavor-changing neutral current process b→dγ using a sample of 386×106 B meson pairs accumulated by the Belle detector at the KEKB e+e- collider. We measure branching fractions for the exclusive modes B-→ρ-γ, B0→ρ0γ, and B0→ωγ. Assuming that these three modes are related by isospin, we find B(B→(ρ,ω)γ)=(1.32-0.31+0.34(stat)-0.09+0.10(syst)) ×10-6 with a significance of 5.1σ. This result is used to determine the ratio of Cabibbo-Kobayashi-Maskawa matrix elements |Vtd/Vts| to be 0.199-0.025+0.026(exp)-0.015+0.018(theor). © 2006 The American Physical Society.

We report measurements of time-dependent decay rates for B{sup 0}{yields}D{sup (*)-}{pi}{sup +} decays and extraction of CP violation parameters that depend on {phi}{sub 3}. Using fully reconstructed D{sup (*)}{pi} events and partially reconstructed D*{pi} events from a data sample that contains 386x10{sup 6} BB pairs that was collected near the {upsilon}(4S) resonance, with the Belle detector at the KEKB asymmetric energy e{sup +}e{sup -} collider, we obtain the CP violation parameters S{sup +}(D{sup (*)}{pi}) and S{sup -}(D{sup (*)}{pi}). We obtain S{sup +}(D*{pi})=0.049{+-}0.020(stat){+-}0.011(sys), S{sup -}(D*{pi})=0.031{+-}0.019(stat){+-}0.011(sys), and S{sup +}(D{pi})=0.031{+-}0.030(stat){+-}0.012(sys), S{sup -}(D{pi})=0.068{+-}0.029(stat){+-}0.012(sys). These results are an indication of CP violation in B{sup 0}{yields}D*{sup -}{pi}{sup +} and B{sup 0}{yields}D{sup -}{pi}{sup +} decays at the 2.5{sigma} and 2.2{sigma} levels, respectively. If we use the values of R{sub D{sup (*}}{pi}} that are derived using assumptions of factorization and SU(3) symmetry, branching fraction measurements for the B{yields}D{sub s}{sup (*)}{pi} modes, and lattice QCD calculations, we can restrict the allowed region of |sin(2{phi}{sub 1}+{phi}{sub 3})| to be above 0.44 and 0.52 at 68% confidence level from the D*{pi} and D{pi} modes, respectively.

- Abstract
We present a measurement of the angle phi1 of the Cabibbo-Kobayashi-Maskawa unitarity triangle using a time-dependent Dalitz analysis of D--KS(0)pi + pi- decays produced in neutral B meson decay to a neutral D meson and a light meson (B0--D*h0). The method allows a direct extraction of 2phi1 and, therefore, helps to resolve the ambiguity between 2phi1 and pi-2phi1 in the measurement of sin2phi1. We obtain sin2phi1= 0.78 +/- 0.44 +/- 0.22 and cos2varphi1 = 1.87(-0.53-0.32)(+0.40 + 0.22). The sign of cos2phi1 is determined to be positive at 98.3% C.L.

We report on a search for new resonant states in the process gamma gamma -> D (D) over bar. A candidate C-even charmonium state is observed in the vicinity of 3.93 GeV/c(2). The production rate and the angular distribution in the gamma gamma center-of-mass frame suggest that this state is the previously unobserved chi(')(c2), the 2(3)P(2) charmonium state.

- Abstract
We report evidence for the exclusive two-body charmless hadronic B meson decay B--eta'pi, and improved measurements of B--eta'K. The results are obtained from a data sample of 386x10(6) BB pairs collected at the Upsilon(4S) resonance, with the Belle detector at the KEKB asymmetric-energy e+e- collider. We measure B(B+--eta'pi+)=[1.76(-0.62)(+0.67)(stat)(-0.14)(+0.15)(syst)]x10(-6) and B(B0--eta'pi0)=[2.79(-0.96)(+1.02)(stat)(-0.34)(+0.25)(syst)]x10(-6). We also find the ratio of B(B+--eta'K+)/B(B0--eta'K0)=1.17+/-0.08(stat)+/-0.03(syst) and measure the direct CP asymmetries for the charged modes.

We report the observation of the flavor-changing neutral current process b--dgamma using a sample of 386 x 106 B meson pairs accumulated by the Belle detector at the KEKB e+e- collider. We measure branching fractions for the exclusive modes B---rho-gamma, B0rho0gamma, and B0omegagamma. Assuming that these three modes are related by isospin, we find B(B--(rho,gamma)gamma)=[Formula: See Text] with a significance of 5.1sigma. This result is used to determine the ratio of Cabibbo-Kobayashi-Maskawa matrix elements /Vtd/Vts/ to be [Formula: See Text].

New images of M31 at 24, 70, and 160 micron taken with the Multiband Imaging Photometer for Spitzer (MIPS) reveal the morphology of the dust in this galaxy. This morphology is well represented by a composite of two logarithmic spiral arms and a circular ring (radius ~10 kpc) of star formation offset from the nucleus. The two spiral arms appear to start at the ends of a bar in the nuclear region and extend beyond the star forming ring. As has been found in previous work, the spiral arms are not continuous but composed of spiral segments. The star forming ring is very circular except for a region near M32 where it splits. The lack of well defined spiral arms and the prominence of the nearly circular ring suggests that M31 has been distorted by interactions with its satellite galaxies. Using new dynamical simulations of M31 interacting with M32 and NGC 205 we find that, qualitatively, such interactions can produce an offset, split ring like that seen in the MIPS images., 7 pages, 4 figures, ApJ Letters, in press (preprint with full resolution images available at http://dirty.as.arizona.edu/~kgordon/papers/PS_files/m31_mips_letter.pdf)

Variable A in M33 is a member of a rare class of highly luminous, evolved stars near the upper luminosity boundary that show sudden and dramatic shifts in apparent temperature due to the formation of optically thick winds in high mass loss episodes. Recent optical and infrared spectroscopy and imaging reveal that its ``eruption'' begun in $\sim$1950 has ended, {\it lasting $\approx$ 45 yrs}. Our current observations show major changes in its wind from a cool, dense envelope to a much warmer state surrounded by low density gas with rare emission lines of Ca II, [Ca II] and K I. Its spectral energy distribution has unexpectedly changed, especially at the long wavelengths, with a significant decrease in its apparent flux, while the star remains optically obscured. We conclude that much of its radiation is now escaping out of our line of sight. We attribute this to the changing structure and distribution of its circumstellar ejecta corresponding to the altered state of its wind as the star recovers from a high mass loss event., Comment: 26 pages, 6 figures

We have studied the dynamics and masses of a sample of ten nearby luminous and ultraluminous infrared galaxies (LIRGS and ULIRGs), using 2.3 micron CO absorption line spectroscopy and near-infrared H- and Ks-band imaging. By combining velocity dispersions derived from the spectroscopy, disk scale-lengths obtained from the imaging, and a set of likely model density profiles, we calculate dynamical masses for each LIRG. For the majority of the sample, it is difficult to reconcile our mass estimates with the large amounts of gas derived from millimeter observations and from a standard conversion between CO emission and H_2 mass. Our results imply that LIRGs do not have huge amounts of molecular gas (10^10-10^11 Msolar) at their centers, and support previous indications that the standard conversion of CO to H_2 probably overestimates the gas masses and cannot be used in these environments. This in turn suggests much more modest levels of extinction in the near-infrared for LIRGs than previously predicted (A_V~10-20 versus A_V~100-1000). The lower gas mass estimates indicated by our observations imply that the star formation efficiency in these systems is very high and is triggered by cloud-cloud collisions, shocks, and winds rather than by gravitational instabilities in circumnuclear gas disks., Comment: 14 pages, 2 figures, accepted to ApJ

We present a measurement of the Cabibbo-Kobayashi-Maskawa matrix element data collected by the Belle detector at the KEKB e+e-asymmetric collider. Events are tagged by fully reconstructing one of the B mesons, produced in pairs from Υ(4S). The signal for b→u semileptonic decay is distinguished from the b→c background using the hadronic mass MX, the leptonic invariant mass squared q2 and the variable P+≡EX-|p→X|. The results are obtained for events with pl*≥1GeV/c, in three kinematic regions (1)MX 8GeV2/c2, and by (3)P+

- Abstract
We report the first observation of a charmoniumlike state recoiling from the J/psi in the inclusive process e+e- --J/psi+anything at a mass of (3.943+/-0.006+/-0.006) GeV/c{2}. We also observe the decay of this state into D*D[over ] and determine its intrinsic width to be less than 52 MeV/c{2} at the 90% C.L. These results are obtained from a 357 fb{-1} data sample collected with the Belle detector near the Upsilon(4S) resonance, at the KEKB asymmetric-energy e+e- collider.

We report on a measurement of the branching fractions for B- → D(*)+π- l -vl and B0 → D (*)0π+l-vl with 275 × 106 BB events collected at the γ(4S) resonance with the Belle detector at KEKB. Events are tagged by fully reconstructing one of the B mesons in hadronic modes. We obtain B(B- → D+π- l-vl = (0.54±0.07(stat)±0.07(syst)±0.06(BR))× 10 -2, B(B- → D(*)+π- l-vl = (0.67 ±0.11(stat) ±0.09(syst) ±0.03(BR)) × 10-2, B(B0 → D0π+ l -vl) = (0.33 ±0.06(stat) ± 0.06(syst) ±0.03(BR)) × 10-2, B(B0 → D(*)0π+l -vl) = (0.65 ±0.12(stat) ± 0.08(syst) ±0.05(BR)) × 10-2, where the third error comes from the error on B → D(*)l -vl decays. Contributions from B0 → D(*)+l-vl decays are excluded in the measurement of B0 → D0π +l-vl. © 2005 The American Physical Society.

We present the results of a study of the charmless vector-vector decay B+ --> rho+ K*0, based on 253 fb(-1) of data collected with the Belle detector at the KEKB asymmetric-energy e+ e- collider. We obtain the branching fraction B(B+ --> rho+ K*0) = [8.9 +/- 1.7(stat) +/- 1.2(syst)] x 10(-6). We also perform a helicity analysis of the rho and K* vector mesons, and obtain the longitudinal polarization fraction f(L)(B+ --> rho+ K*0) = 0.43 +/- 0.11(stat)(-0.02)(+0.05) (syst).

We report the observation of B-→J/ψΛp and searches for B-→J/ψΣ0p and B0→J/ψpp decays, using a sample of 275×106 BB pairs collected with the Belle detector at the Υ(4S) resonance. We observe a signal of 17.2±4.1 events with a significance of 11.1σ and obtain a branching fraction of B(B-→J/ψΛp)=11.6±2.8(stat)-2.3+1.8(sys)×10-6. No signal is found for either of the two decay modes, B-→J/ ψΣ0p and B0→J/ψpp, and upper limits for the branching fractions are determined to be B(B-→J/ψΣ0p)

We present a new measurement of the time-dependent CP-violating parameters in B{sup 0}{yields}{pi}{sup +}{pi}{sup -} decays with 275x10{sup 6} BB pairs collected with the Belle detector at the KEKB asymmetric-energy e{sup +}e{sup -} collider operating at the {upsilon}(4S) resonance. We find 666{+-}43 B{sup 0}{yields}{pi}{sup +}{pi}{sup -} events and measure the CP-violating parameters: S{sub {pi}}{sub {pi}}=-0.67{+-}0.16(stat){+-}0.06(syst) and A{sub {pi}}{sub {pi}}=+0.56{+-}0.12(stat){+-}0.06(syst). We find evidence for large direct CP violation with a significance greater than 4 standard deviations for any S{sub {pi}}{sub {pi}} value. Using isospin relations, we obtain 95.4% confidence intervals for the Cabibbo-Kobayashi-Maskawa quark-mixing matrix angle {phi}{sub 2} of 0 deg.

CP violation in B-->J/PsiK* decays is studied using an angular analysis in a data sample of 253 fb(-1) recorded with the Belle detector at the KEKB e(+)e(-) collider. The flavor separated measurements of the decay amplitudes indicate no evidence for direct CP violation. T-odd CP violation is studied using the asymmetries in triple product correlations, and the results are consistent with the standard model null predictions. The time-dependent angular analysis gives the following values of CP-violating parameters: sin(2phi(1) = 0.24 +/- 0.31 +/- 0.05 and cos(2phi(1)=0.56 +/- 0.79 +/- 0.11.

We report measurements of B meson decays to two kaons using 250/fb of data collected with the Belle detector at the KEKB asymmetric energy e+ e- collider. We find evidence of signals in B+ -> K0(bar) K+ and B0 -> K0 K0(bar) with significances of 3.0 sigma and 3.5 sigma, respectively. The corresponding branching fractions are measured to be BF(B+ -> K0(bar) K+) = (1.0+-0.4+-0.1) x 10^-6 and Br(B0 -> K0 K0(bar)) = 0.8+-0.3+-0.1) x 10^-6. These decay modes are examples of hadronic b -> d transitions. No signal is observed in the decay B0 -> K+ K- and we set an upper limit of 3.7 x 10^-7 at 90% confidence level., 8 pages, 1 figure, submitted to the Lepton Photon 2005 conference in Uppsala, Sweden and to the HEP2005 Europhysics Conference in Lisbon, Portugal Submitted to PRL

We report evidence for B{sup 0}{yields}D{sup +}D{sup -} and the first observation of the decay modes B{sup -}{yields}D{sup 0}D{sup -} and B{sup -}{yields}D{sup 0}D{sup *-} based on a sample of 152x10{sup 6} BB events collected by the Belle detector at KEKB. The branching fractions for B{sup 0}{yields}D{sup +}D{sup -}, B{sup -}{yields}D{sup 0}D{sup -}, and B{sup -}{yields}D{sup 0}D{sup *-} are found to be (1.91{+-}0.51{+-}0.30)x10{sup -4} (4.83{+-}0.78{+-}0.58)x10{sup -4}, and (4.57{+-}0.71{+-}0.56)x10{sup -4}, respectively. Charge asymmetries in the B{sup -}{yields}D{sup 0}D{sup -} and B{sup -}{yields}D{sup 0}D{sup *-} channels are consistent with zero.

We present new measurements of CP-violation parameters in B0→K0, K+K-KS0, f0(980)KS0, η′KS0, ωKS0, and KS0π0 decays based on a sample of 275×106 BB pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. One neutral B meson is fully reconstructed in one of the specified decay channels, and the flavor of the accompanying B meson is identified from its decay products. CP-violation parameters for each of the decay modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays. The combined result for the B0→K0, K+K-KS0, f0(980)KS0, η′KS0, ωKS0, KS0π0, and previously reported KS0KS0KS0 decays differs from the SM expectation by 2.4 standard deviations. © 2005 The American Physical Society.

We present a new measurement of CP-violation parameters in B(0)-->K(0)(S)pi(0)gamma decay based on a sample of 275 x 10(6) BB pairs collected at the Gamma(4S) resonance with the Belle detector at the KEKB energy-asymmetric e(+)e(-) collider. One of the B mesons is fully reconstructed in the B(0)-->K(0)(S)pi(0)gamma decay. The flavor of the accompanying B meson is identified from its decay products. CP-violation parameters are obtained from the asymmetry in the distribution of the proper time intervals between the two B decays. We obtain SK(0)(S)(pi(0)gamma) = -0.58(+0.46)(-0.38)(stat) +/- 0.11(syst) and AK(0)(S)(pi(0)gamma) = +0.03 +/- 0.34(stat) +/- 0.11(syst), for the K(0)(S)pi(0) invariant mass covering the full range up to 1.8 GeV/c2. We also measure the CP-violation parameters for the case B(0)-->K(*0)(-->K(0)(S)pi(0))gamma and obtain S(K(*0)gamma) = -0.79(+0.63)(-0.50)(stat) +/- 0.10(syst) for A(K(*0)gamma) fixed at 0.

We report on the first observation of D10(2420)→D0π-π+ and D1+(2420)→D+π-π+ decays (where the contribution from the dominant known D1→D*π decay mode is excluded) in the B-→D10π- and B0→D1+π- decays, respectively. The observation is based on 15.2×107 BB events collected with the Belle detector at the KEKB collider. We also set 90% confidence level upper limits for the branching fractions of the four following decays: B-→D10π-, D10→D *0π-π+, B0→D1+π-, D1+→D*+π-π+, B-→D2*0(2460)π-, D2*0→D*0π-π+, B0→D2*+(2460)π-, D2*+→D*+π-π+. © 2005 The American Physical Society.

Two images of Cassiopeia A obtained at 24 micrometer with the Spitzer Space Telescope over a one year time interval show moving structures outside the shell of the supernova remnant to a distance of more than 20 arcmin. Individual features exhibit apparent motions of 10 to 20 arcsec per year, independently confirmed by near-infrared observations. The observed tangential velocities are at roughly the speed of light. It is likely that the moving structures are infrared echoes, in which interstellar dust is heated by the explosion and by flares from the compact object near the center of the remnant., To be published in Science on June 10, 2005. 11 pages, 4 figures.

We present measurements of decay amplitudes and triple-product correlations in B-->phiK* decays based on 253 fb(-1) of data recorded at the Upsilon(4S) resonance with the Belle detector at the KEKB e(+)e(-) storage ring. The decay amplitudes for the three different helicity states are determined from the angular distributions of final-state particles. The longitudinal polarization amplitudes are found to be 0.45 +/- 0.05 +/- 0.02 for B0-->phiK(*0) and 0.52 +/- 0.08 +/- 0.03 for B+ -->phiK(*+) decays. CP- and T-odd CP-violating triple-product asymmetries are measured to be consistent with zero.

We report results on the Dalitz analysis of three-body charmless B+ -> K+ pi(+) pi(-) and B+-> K+ K+ K- decays based on a 140 fb(-1) data sample collected with the Belle detector. Measurements of branching fractions for quasi-two-body decays to scalar-pseudoscalar states: B+ -> f(0)(980)K+, B+ -> K-0(*)(1430)(0)pi(+), and to vector-pseudoscalar states: B+ -> K-*(892)(0)pi(+), B+ -> rho(0)K(+), B+ -> phi K+ are presented. Upper limits on decays to some pseudoscalar-tensor final states are reported. We also report the measurement of the B+ -> chi(c0)K(+) branching fraction in two chi(c0) decays channels: chi(c0) -> pi(+)pi(-) and chi(c0) -> K+K-.

We report the observation of the decay B0-->pi(0)pi(0), using a 253 fb(-1) data sample collected at the Upsilon(4S) resonance with the Belle detector at the KEKB e(+)e(-) collider. The measured branching fraction is B(B0-->pi(0)pi(0))=(2.3(+0.4+0.2)(-0.5-0.3))x10(-6), with a significance of 5.8 standard deviations including systematic uncertainties. We also make a measurement of the direct CP violating asymmetry in this mode.
