Abstract

The properties of three-jet events with total transverse energy greater than 320 GeV and individual jet energy greater than 20 GeV have been analyzed and compared to absolute predictions from a next-to-leading order (NLO) perturbative QCD calculation. These data, of integrated luminosity 86 pb^-1, were recorded by the CDF Experiment for proton-antiproton collisions at sqrt{s}=1.8 TeV. This study tests a model of higher order QCD processes that result in gluon emission and can be used to estimate the magnitude of the contribution of processes higher than NLO. The total cross section is measured to be 466 +/- 3(stat.)^{+207}_{-70}(syst.) pb. The differential cross section is furthermore measured for all kinematically accessible regions of the Dalitz plane, including those for which the theoretical prediction is unreliable. While the measured cross section is consistent with the theoretical prediction in magnitude, the two differ somewhat in shape in the Dalitz plane.

Abstract

We present a measurement of relative partial widths and decay rate CP asymmetries in K−K+ and π−π+ decays of D0 mesons produced in pp¯ collisions at s√=1.96 TeV. We use a sample of 2×105 D*+→D0π+ (and charge conjugate) decays with the D0 decaying to K−π+, K−K+, and π−π+, corresponding to 123 pb−1 of data collected by the Collider Detector at Fermilab II experiment at the Fermilab Tevatron collider. No significant direct CP violation is observed. We measure Γ(D0→K−K+)/Γ(D0→K−π+)=0.0992±0.0011±0.0012, Γ(D0→π−π+)/Γ(D0→K−π+)=0.035 94±0.000 54±0.000 40, ACP(K−K+)=(2.0±1.2±0.6)%, and ACP(π−π+)=(1.0±1.3±0.6)%, where, in all cases, the first uncertainty is statistical and the second is systematic.

Abstract

We present a search for long-lived doubly charged Higgs bosons (H±±), with signatures of high ionization energy loss and muonlike penetration. We use 292 pb−1 of data collected in pp¯ collisions at √s=1.96 TeV by the CDF II detector at the Fermilab Tevatron. Observing no evidence of long-lived doubly charged particle production, we exclude H±±L and H±±R bosons with masses below 133 GeV/c2 and 109 GeV/c2, respectively. In the degenerate case we exclude H±± mass below 146 GeV/c2. All limits are quoted at the 95% confidence level.

21. Hysteresis effects in instantaneous frequency scaling of attenuation on 20 and 30 GHz satellite links

Abstract

It has been observed with 20/30 GHz satellite beacon measurements that the ratio of 30 GHz to 20 GHz attenuation changes during some fade events. This ratio displays a hysteresis effect. This effect can be explained by a change in the drop size distribution (DSD) during the event. However, it appears only above approximately 6-8 dB of attenuation at 20 GHz. Instantaneous frequency scaling of attenuation is being proposed as part of an algorithm for uplink power control (ULPC) and the dynamic range of such an algorithm must be appropriately limited to avoid the hysteresis.

Abstract

A major propagation experiment is in progress to measure atmospheric attenuation at 12, 20, and 30 GHz using the beacons of the Olympus satellite. The experiment uses a frequency-locked receiver system which locks to the 12-GHz beacon frequency and measures the signal strength of the coherent 20- and 30-GHz beacons in a 3-Hz bandwidth. The receiving system is augmented with radiometers in each beacon frequency band to set the clear-air attenuation levels of the beacon signals. Olympus propagation experiment objectives and the measurement system are described. Results from the measurement program will include fade statistics at all frequencies, attenuation scaling between frequencies, short baseline site diversity, and fade dynamics.

28. FGF8 morphogen gradients are differentially regulated by heparan sulphotransferases Hs2st and Hs6st1 in the developing brain.

Abstract

Fibroblast growth factor (FGF) morphogen signalling through the evolutionarily ancient extracellular signalling-regulated kinase/mitogen activated protein kinase (ERK/MAPK) pathway recurs in many neural and non-neural developmental contexts, and understanding the mechanisms that regulate FGF/ERK function are correspondingly important. The glycosaminoglycan heparan sulphate (HS) binds to FGFs and exists in an enormous number of differentially sulphated forms produced by the action of HS modifying enzymes, and so has the potential to present an extremely large amount of information in FGF/ERK signalling. Although there have been many studies demonstrating that HS is an important regulator of FGF function, experimental evidence on the role of the different HS modifying enzymes on FGF gradient formation has been lacking until now. We challenged ex vivo developing mouse neural tissue, in which HS had either been enzymatically removed by heparanase treatment or lacking either the HS modifying enzymes Hs2st (Hs2st-/- tissue) or Hs6st1 (Hs6st1-/- tissue), with exogenous Fgf8 to gain insight on how HS and the function of these two HS modifying enzymes impacts on Fgf8 gradient formation from an exogenously supplied source of Fgf8 protein. We discover that two different HS modifying enzymes, Hs2st and Hs6st1, indeed differentially modulate the properties of emerging Fgf8 protein concentration gradients and the Erk signalling output in response to Fgf8 in living tissue in ex vivo cultures. Both Hs2st and Hs6st1 are required for stable Fgf8 gradients to form as rapidly as they do in wild-type tissue while only Hs6st1 has a significant effect on suppressing the levels of Fgf8 protein in the gradient compared to wild type. Next we show that Hs2st and Hs6st1 act to antagonise and agonise the Erk signalling in response to Fgf8 protein, respectively, in ex vivo cultures of living tissue. Examination of endogenous Fgf8 protein and Erk signalling outputs in Hs2st-/- and Hs6st1-/- embry

34. Paleoseismologic evidence for large-magnitude (M-w 7.5-8.0) earthquakes on the Ventura blind thrust fault: Implications for multifault ruptures in the Transverse Ranges of southern California

Abstract

Detailed analysis of high-resolution seismic reflection data, continuously cored boreholes\ud and cone penetrometer tests (CPTs), and luminescence and 14 C dates from Holocene strata folded\ud above the tip of the Ventura blind thrust fault constrain the ages and displacements in the two\ud most recent earthquakes. These two earthquakes are recorded by a prominent surface fold scarp\ud and a stratigraphic sequence that thickens across an older buried fold scarp, and occurred soon\ud after about 700-900 years ago (most recent event) and between 3-5 ka (penultimate event).\ud Minimum uplift in these two scarp-forming events was ~6 m for the most recent earthquake and\ud ~4.5 meters for the penultimate event. Individual uplifts of this amount require large magnitude \ud earthquakes, probably in excess of Mw7.5 and likely involving rupture of the Ventura fault\ud together with other Transverse Ranges faults to the east and west. The proximity of this large\ud reverse-fault system to major population centers, including the greater Los Angeles region, and\ud the potential for tsunami generation during ruptures extending offshore along the western parts\ud of the system, highlight the importance of understanding the complex behavior of these faults for\ud probabilistic seismic hazard assessment.

Abstract

Freshwater eels Anguilla spp. are declining worldwide, and a major challenge is understanding why these panmictic species show contrasting patterns of intraspecific phenotypic variation and recruitment. We present results on studies of the American Eel A. rostrata to understand and discriminate the effects of origin and plasticity on growth and sex determination. We considered two separate growth and one length-at-age data sets. The first growth data set originated from a 34-month rearing experiment starting from the glass eel life stage to test the effects of origin, salinity, and density on growth and sex determination. The second growth data set originated from a shorter rearing experiment of 18 months starting at the yellow eel stage (around 3 years old) and compared transplanted individuals in Lake Ontario (LO) with natural migrants to the LO area. The third data set compared transplanted individuals in LO sampled by electrofishing with naturally migrating individuals. Sex ratios were identical for all origins and treatments in the long-term growth experiment (34–35% females). While male size distribution had little variability, certain female groups had a large variation in growth and presented fast- and slow-growing clusters. On the other hand, both cases of natural migrants to the LO area were consistent with being only slow-growing females. We found that wild individuals rearing in the LO area were nearly exclusively transplanted individuals and that males, as well as fast-growing females, were present. Even though the entire species is panmictic, these results support a role for spatially varying selection in explaining the phenotypic variation observed among regions and among individuals of the same region, and such factors must be considered for any successful management strategies of American Eel.

Abstract

We present a measurement of the mass dependence of the forward-backward charge asymmetry (A(FB)) for e(+)e(-) pairs produced via an intermediate Z/gamma(*) with mass M-ee > 40 GeV/c(2). We study the constraints on the Z-quark couplings imposed by our measurement. We analyze an integrated luminosity of 72 pb(-1) collected by the CDF-II detector in (p) over barp collisions at root s = 1.96 TeV at the Fermilab Tevatron. A comparison of the uncorrected AFB between data and standard model Monte Carlo gives good agreement with a chi(2)/DOF of 15.7/15. The couplings measurements are also consistent with standard model predictions.

Abstract

We present the results of a search for anomalous production of diphoton events with large missing transverse energy using the Collider Detector at Fermilab. In 202 pb(-1) of p (p) over bar collisions at s=1.96 TeV we observe no candidate events, with an expected standard model background of 0.27+/-0.07(stat)+/-0.10(syst) events. The results exclude a lightest chargino of mass less than 167 GeV/c(2), and lightest neutralino of mass less than 93 GeV/c(2) at 95% C.L. in a gauge-mediated supersymmetry-breaking model with a light gravitino.

Abstract

We present a measurement of the mass dependence of the forward-backward charge asymmetry (A(FB)) for e(+)e(-) pairs produced via an intermediate Z/gamma(*) with mass M(ee) > 40 GeV/c(2). We study the constraints on the Z-quark couplings imposed by our measurement. We analyze an integrated luminosity of 72 pb(-1) collected by the CDF-II detector in (p) over barp collisions at root s = 1.96 TeV at the Fermilab Tevatron. A comparison of the uncorrected AFB between data and standard model Monte Carlo gives good agreement with a chi(2)/DOF of 15.7/15. The couplings measurements are also consistent with standard model predictions.

Abstract

We report a measurement of the t (t) over bar production cross section using the CDF II detector at the Fermilab Tevatron. The data consist of events with an energetic electron or muon, missing transverse energy, and three or more hadronic jets, at least one of which is identified as a b-quark jet by reconstructing a secondary vertex. The background fraction is determined from a fit of the transverse energy of the leading jet. Using 162 +/- 10 pb(-1) of data, the total cross section is found to be 6.0 +/- 1.6(stat.)+/- 1.2(syst.) pb, which is consistent with the standard model prediction.

Abstract

We report a measurement of the forward-backward charge asymmetry of electrons from W boson decays in p (p) over bar collisions root s = 1.96 TeV using a data sample of 170 pb(-1) collected by the Collider Detector at Fermilab. The asymmetry is measured as a function of electron rapidity and transverse energy and provides new input on the momentum fraction dependence of the u and d quark parton distribution functions within the proton.

Abstract

We present a search for ZZ and ZW vector boson pair production in p (p) over bar collisions at root z = 1.96 TeV using the leptonic decay channels ZZ -> ll nu nu, ZZ -> lll(')l('), and ZW -> lll(')v. In a data sample corresponding to an integrated luminosity of 194 pb(-1) collected with the Collider Detector at Fermilab, 3 candidate events are found with an expected background of 1.0 +/- 0.2 events. We set a 95% confidence level upper limit of 15.2 pb on the cross section for ZZ plus ZW production, compared to the standard model prediction of 5.0 +/- 0.4 pb.

Abstract

We present a search for ZZ and ZW vector boson pair production in p (p) over bar collisions at root z = 1.96 TeV using the leptonic decay channels ZZ -> ll nu nu, ZZ -> lll(')l('), and ZW -> lll(')v. In a data sample corresponding to an integrated luminosity of 194 pb(-1) collected with the Collider Detector at Fermilab, 3 candidate events are found with an expected background of 1.0 +/- 0.2 events. We set a 95% confidence level upper limit of 15.2 pb on the cross section for ZZ plus ZW production, compared to the standard model prediction of 5.0 +/- 0.4 pb.

Abstract

We present a measurement of the W+W- production cross section using 184 pb(-1) of p (p) over bar collisions at a center-of-mass energy of 1.96 TeV collected with the Collider Detector at Fermilab. Using the dilepton decay channel W+W-→ l(+)ν l(-)(ν) over bar, where the charged leptons can be either electrons or muons, we find 17 candidate events compared to an expected background of 5.0(-0.8)(+2.2) events. The resulting W+W- production cross-section measurement of σ(p (p) over bar → W+W-)=14.6(-5.1)(+5.8)(stat)(-3.0)(+1.8)(syst)± 0.9(lum) pb agrees well with the standard model expectation.

Abstract

We present a search for long-lived doubly charged Higgs bosons (H(+/-+/-)), with signatures of high ionization energy loss and muonlike penetration. We use 292 pb(-1) of data collected in p (p) over bar collisions at root s=1.96 TeV by the CDF II detector at the Fermilab Tevatron. Observing no evidence of long-lived doubly charged particle production, we exclude H(L)(+/-+/-) and H(R)(+/-+/-) bosons with masses below 133 GeV/c(2) and 109 GeV/c(2), respectively. In the degenerate case we exclude H(+/-+/-) mass below 146 GeV/c(2). All limits are quoted at the 95% confidence level.

We report a measurement of the forward-backward charge asymmetry of electrons from W boson decays in p (p) over bar collisions root s = 1.96 TeV using a data sample of 170 pb(-1) collected by the Collider Detector at Fermilab. The asymmetry is measured as a function of electron rapidity and transverse energy and provides new input on the momentum fraction dependence of the u and d quark parton distribution functions within the proton.

Abstract

Using 180 pb(-1) of data collected with the CDF II detector at the Tevatron, we measure the first two moments of the hadronic invariant mass-squared distribution in charmed semileptonic B decays. From these we determine the nonperturbative Heavy Quark Effective Theory parameters Lambda and lambda(1) used to relate the B meson semileptonic branching ratio to the CKM matrix element vertical bar V(ch)vertical bar. For a minimum lepton momentum of 0.7 GeV/c in the B rest frame we measure the first two moments of the D(**) -> D((*))pi component to be < m(D**)(2)> = (5.83 +/- 0.16(stat) +/- 0.08(syst)) GeV(2)/c(4) and )(2)> = (130 +/- 0.69(stat) +/- 0.22(syst)) GeV(4)/c(8). Combining these with the discrete mass terms from the D and D* mesons, we find the total moments to be < M(Xc)(2)> - (m) over bar (2)(D) = (0.467 +/- 0.038(stat) +/- 0.068(syst)) GeV(2)/c(4) and )(2)) = (1.05 +/- 0.26(stat) +/- 0.13(syst)) GeV(4)/c(8), where (m) over bar (2)(D) is the spin-averaged D mass. The systematic error is dominated by the uncertainties in the world-average branching ratios used to combine the D, D*, and D** contributions. The analysis makes no assumptions about the shape or resonant structure of the D(**) -> D((*))pi invariant mass distribution.

Abstract

We present measurements of the lifetimes and polarization amplitudes for B(s)(0)-> J/psi phi and B(d)(0)-> J/psi K(*0) decays. Lifetimes of the heavy and light mass eigenstates in the B(s)(0) system are separately measured for the first time by determining the relative contributions of amplitudes with definite CP as a function of the decay time. Using 203 +/- 15 B(s)(0) decays we obtain tau(L)=(1.05(-0.13)(+0.16)+/- 0.02) ps and tau(H)=(2.07(-0.46)(+0.58)+/- 0.03) ps. Expressed in terms of the difference Delta Gamma(s) and average Gamma(s), of the decay rates of the two eigenstates, the results are Delta Gamma(s)/Gamma(s)=(65(-33)(+25)+/- 1)% and Delta Gamma(s)=(0.47(-0.24)(+0.19)+/- 0.01) ps(-1).

Abstract

Using 180 pb^-1 of data collected with the CDF II detector at the Tevatron, we measure the first two moments of the hadronic invariant mass-squared distribution in charmed semileptonic B decays. From these we determine the non-perturbative Heavy Quark Effective Theory parameters Lambda and lambda_1, used to relate the B meson semileptonic branching ratio to the CKM matrix element |V_cb|. For a minimum lepton momentum of 0.7 GeV/c in the B rest frame me measure the first two moments of the D** --> D(*) pi component to be = (5.83 +/- 0.16(stat) +/- 0.08(syst)) GeV^2, )^2> = (1.30 +/- 0.69(stat) +/- 0.22(syst)) GeV^4. Combining these with the discrete mass terms from the D and D* mesons, we find the total moments to be - mbar_D^2 = (0.467 +/- 0.038_(stat) +/- 0.068(syst)) GeV^2, )^2> = (1.05 +/- 0.26(stat) +/- 0.13(syst)) GeV^4, where mbar_D is the spin-averaged D mass. The systematic error is dominated by the uncertainties in the world-average branching ratios used to combine the D, D* and D** contributions. The analysis makes no assumptions about the shape or resonant structure of the D** --> D(*) pi invariant mass distribution., Comment: 9 pages, 3 figures, 1 table. Accepted by PRDRC for publication.
