Abstract: We constructed a new forward calorimeter which covers a small polar angular region in the TOPAZ detector at the TRISTAN e + e − storage ring of KEK. It comprises large BGO crystals with a silicon photodiode readout system for energy measurements, and silicon strip detectors for position measurements. It has been operating since November 1989. We present detailed design considerations and the performance from test beam measurements and e + e − colliding beam experiments. We also show the results of luminosity measurements and discuss the systematic errors.

Abstract: The process e + e − →e + e − μ + μ − has been studied in single-tag and double-tag configurations using the TOPAZ detector at TRISTAN. The data correspond to the integrated luminosity of 45.3pb − at center-of-mass energies ranging from 52 to 61.4 GeV. The observed events in both configurations have shown a good agreement with QED predictions in order α 4 . Although the AMY group reported an excess of e + e − →e + e − μ + μ − events in double-tag mode at low muon invariant mass region less than 1.0 GeV/c 2 , we did not observed such excess in our data.

Abstract: An experimental study of b-quark jets using high-pT electrons was carried out at √s=58 GeV with the TOPAZ detector at the e+e− collider TRISTAN at KEK. The forward-backward charge asymmetry of the b-quark was obtained to be A b b =−0.55±0.27( stat. )±0.07( syst. ) , consistent with the standard model prediction. Also, such jet properties of the b-quark as the average charged multiplicity and the rapidity of charged particles were analyzed. In order to purify the b-quark event samples in this analysis, only events with backward-going electrons or forward-going positrons were used. The energy dependence of these jet properties was studied by making comparisons with the results of the DELCO experiment at the PEP collider (√s=29 GeV) at SLAC.

Abstract: Pre- and postoperative MR findings in the spinal cord of 4 patients who underwent lesioning of the cervical dorsal root entry zone (DREZ-otomy) are reported. In 3 patients with root avulsion, MR images revealed spinal cord atrophy preoperatively and, after DREZ-otomy, long-lasting spinal cord enlargement and extensive intramedullary changes. In a case without root avulsion, the preoperative MR study showed no apparent abnormality and the only postoperative MR change was a discrete lesion well confined to the dorsal horn. The findings suggested basically different post-operative pathology among patients with root avulsion and those without. MRI can be a useful supplement to autopsy study in defining postoperative spinal cord changes after DREZ-otomy.

155. Role of external and internal perturbations on the ferromagnetic phase transition inSm0.52Sr0.48MnO3

Abstract: We report on the magnetic field (H), hydrostatic pressure (P), and doping dependence of the order of the ferromagnetic (FM) to paramagnetic (PM) phase transition in Sm0.52Sr0.48MnO3 single crystal. It has been shown that (H-cr approximate to 4 T, T-cr approximate to 160 K) is a critical point below which FM to PM phase transition is first order in nature accompanied by a sharp drop in resistivity and magnetization with thermal hysteresis. Below the critical point, these parameters also show field-induced metamagnetic transition along with hysteresis between the increasing and decreasing fields. All these signatures of first-order FM transition disappear above the critical point and the transition becomes a crossover. The effect of P on the nature of FM-PM transition is quite similar to that of H and the corresponding critical point, where the character of FM transition that changes from first to second order is (P-cr approximate to 2.5 GPa, T-cr approximate to 160 K). We have also determined the location of critical point expressed in terms of Nd concentration (y) of (Sm1-yNdy)(0.52)Sr0.48MnO3 and found that the transition changes to second order at (y(cr)approximate to 0.4, T-cr approximate to 175 K). The change in the character of FM transition with the application of external (H and P) and internal (Nd concentration) perturbations has been explained within the framework of the formation of polarons.

Abstract: This paper models and analyzes the stability of a slotted-ALOHA network hosting heterogeneous users. The scheme is modeled by dividing the total user-population into groups of homogeneous users. The behavior of the system is represented by state equations. The stability analysis is carried out by Liapunov's indirect method, in association with the properties of M-matrix, to obtain the sufficient condition for the structural stability of the networks. The analysis also points out the method of hierarchical grouping of the heterogeneous users.

Abstract: We have collected 122 multi-hadronic inclusive muon events with the TOPAZ detector at 〈s〉 = 58.27 GeV with ∫Ldt=40.61 pb−1. From this event sample we derived the differential cross section for B-hadron productions and determined B-hadron forward-backward asymmetry (Abb) to be Abb = −0.71 ± 0.34 (stat)+0.07−0.08(syst). A fit to the differential cross section, after correcting for the effect of B0B0 mixing, yielded the axial-vector coupling constant of the b-quark (ab):ab = −1.79+0.34−0.32(stat)+0.15−0.14(syst).

Abstract: An attempt is made to design a user-friendly software environment for protocol synthesis based on the FSM (finite state machine), and to show the validity of applying AI (artificial intelligence) techniques to the construction of such a system. For that purpose, the authors have first designed a user-friendly software environment, named SEPS, using the programming language C, which belongs to the procedural programming paradigm. The aim of SEPS is to help a protocol designer to easily design a protocol and avoid logical errors like unspecified receptions and state deadlocks. In order to enhance the productivity of protocol development, a user-friendly interface has been designed which employs the multiwindow mechanism and provides the graphic tools in this system. Consequently, a protocol designer without any experience in protocol synthesis can easily design a protocol without logical errors. The authors have also designed a knowledge-based software environment for protocol synthesis, named KSPS, using the expert system tool OPS83. KSPS has the same functions as SEPS. The advantages of KSPS over SEPS in terms of extension, modification, and maintenance of protocol development systems are shown. >

Abstract: A numerical method is suggested for estimating the performance parameters of a node with input buffer limiting, throughout the range of blocking probabilities. Congestion is attributed to the sudden increase in the effective service time when the input rate increases. This sudden increase, resulting in the thrashing of the throughput rate, can be related to changes in the shape of the potential function of the node. The methodology of deriving the potential function of the node from its gradient dynamics and dynamic flow conservation considerations is presented. Using the results from catastrophe theory, it is shown that the abrupt changes in the throughput can be expected due to the existence of a catastrophe point in the parameter space. The behavior of a node in a homogeneous network can be characterized by a fold catastrophe. The simulation results are found to agree with the results obtained by the numerical method. >

Abstract: We report a measurement of the exclusive e+ e- -->Lambda+_(c)Lambda-_(c) cross section as a function of center-of-mass energy near the Lambda+_(c)Lambda-_(c) threshold. A clear peak with a significance of 8.2sigma is observed in the Lambda+_(c)Lambda-_(c) invariant mass distribution just above threshold. With an assumption of a resonance origin for the observed peak, a mass and width of M=[4634 (+8)_(-7)(stat)(+5)_(-8)(syst)] MeV/c(2) and Gamma_(tot)=[92 (+40)_(-24)(stat)(+10)_(-21)(syst)] MeV are determined. The analysis is based on a study of events with initial-state-radiation photons in a data sample collected with the Belle detector at the Upsilon(4S) resonance and nearby continuum with an integrated luminosity of 695 fb(-1) at the KEKB asymmetric-energy e+ e- collider.

Abstract: Using the previous Belle measurement of the inclusive photon energy in B→Xsγ decays, we determine the first and second moments of this spectrum for minimum photon energies in the B meson rest frame ranging from 1.8 to 2.3 GeV. Combining these measurements with recent Belle data on the lepton energy and hadronic mass moments in B→Xclν decays, we perform fits to theoretical expressions derived in the 1S and kinetic mass schemes and extract the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element Vcb, the b-quark mass, and other nonperturbative parameters. In the 1S scheme analysis we find |Vcb|=(41.56±0.68(fit)±0.08(τB))×10-3 and mb1S=(4.723±0.055)GeV. In the kinetic scheme, we obtain |Vcb|=(41.58±0.69(fit)±0.08(τB)±0.58(th))×10-3 and mbkin=(4.543±0.075)GeV. © 2008 The American Physical Society.

Abstract: We report a measurement of the exclusive e+ e- --Lambda+_(c)Lambda-_(c) cross section as a function of center-of-mass energy near the Lambda+_(c)Lambda-_(c) threshold.

With an assumption of a resonance origin for the observed peak, a mass and width of M=[4634 (+8)_(-7)(stat)(+5)_(-8)(syst)] MeV/c(2) and Gamma_(tot)=[92 (+40)_(-24)(stat)(+10)_(-21)(syst)] MeV are determined.

167. Emerinopathy and laminopathy clinical, pathological and molecular features of muscular dystrophy with nuclear envelopathy in Japan

Abstract: Mutations in the genes for nuclear envelope proteins of emerin (EMD) and lamin A/C (LMNA) are known to cause Emery-Dreifuss muscular dystrophy (EDMD) and limb girdle muscular dystrophy (LGMD). We compared clinical features of the muscular dystrophy patients associated with mutations in EMD (emerinopathy) and LMNA (laminopathy) in our series. The incidence of laminopathy was slightly higher than that of emerinopathy. The age at onset of the disease in emerinopathy was variable and significantly older than in laminopathy. The initial symptom of emerinopathy was also variable, whereas nearly all laminopathy patients presented initially with muscle weakness. Calf hypertrophy was often seen in laminopathy, underscoring the importance of mutation screening for LMNA in childhood muscular dystrophy with calf hypertrophy. The clinical spectrum of emerinopathy is actually wider than previously known including EDMD, LGMD, conduction defects with minimal muscle/joint involvement, and their intermittent forms. Pathologically, no marked difference was observed between emerinopathy and laminopathy. Increased number and variation in size of myonuclei were detected. More precise observations using electron microscopy is warranted to characterize the detailed nuclear changes in nuclear envelopathy.

Abstract: Caveolin-3 is a muscle-specific membrane protein that serves as a scaffold of various molecules. As previously reported, caveolin-3 deficiency causes muscle degeneration in mice. In the present study, gene expression profiles, analyzed in the skeletal muscles of caveolin-3 deficient mice using the DNA microarray technique, showed that the gene of osteopontin, a versatile regulator of inflammation and tissue repair, was significantly down-regulated. This is in contrast to mdx mice showing a markedly up-regulated osteopontin gene in their skeletal muscles. Recently, osteopontin has been reported to be important in the pathogenesis of muscular dystrophy. We examined whether up-regulated osteopontin gene expression in mdx muscles is altered by the deficiency of caveolin-3. To this end, we developed caveolin-3 and dystrophin double-deficient mice and used them for the analysis. Levels of osteopontin mRNA and protein in the double-deficient mice clearly decreased compared with those in mdx mice.

Abstract: We present a measurement of the branching fraction $B(D_s^+\to\mu^+\nu_\mu)$ using a 548 fb$^{-1}$ data sample collected by the Belle experiment at the KEKB $e^+e^-$ collider. The $D_s$ momentum is determined by reconstruction of the system recoiling against $DK\gamma X$ in events of the type $e^+e^-\to D_s^\ast DKX, D_s^\ast \to D_s\gamma$, where $X$ represents additional pions or photons from fragmentation. The full reconstruction method provides high resolution in the neutrino momentum and thus good background separation, equivalent to that reached by experiments at the tau-charm factories. We obtain the branching fraction $B(D_s^+\to\mu^+\nu_\mu) = (6.44 \pm 0.76({\rm stat}) \pm 0.57({\rm syst})) \cdot 10^{-3}$, implying a $D_s$ decay constant of $f_{D_s} = (275 \pm 16({\rm stat}) \pm 12({\rm syst}))$ MeV.

Abstract: We report a study of the processes e+e-→J/ψD(*)D(*). In J/ψD*D* we observe a significant enhancement in the D*D* invariant mass spectrum, which we interpret as a new charmoniumlike state and denote X(4160). The X(4160) parameters are M=(4156-20+25±15)MeV/c2 and Γ=(139-61+111±21)MeV. We also report a new measurement of the X(3940) mass and width: M=(3942-6+7±6) MeV/c2 and Γ=(37-15+26±8)MeV.

Abstract: We report improved measurements of time-dependent CP violation parameters for B{sup 0}(B{sup 0}){yields}{psi}(2S)K{sub S}{sup 0}. This analysis is based on a data sample of 657x10{sup 6} BB pairs collected at the {upsilon}(4S) resonance with the Belle detector at the KEKB energy-asymmetric e{sup +}e{sup -} collider. We fully reconstruct one neutral B meson in the {psi}(2S)K{sub S}{sup 0} CP-eigenstate decay channel, and the flavor of the accompanying B meson is identified to be either B{sup 0} or B{sup 0} from its decay products. CP violation parameters are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays: S{sub {psi}}{sub (2S)K{sub S{sup 0}}=+0.72{+-}0.09(stat){+-}0.03(syst), A{sub {psi}}{sub (2S)}K{sub S{sup 0}}=+0.04{+-}0.07(stat){+-}0.05(syst). These results are in agreement with results from measurements of B{sup 0}{yields}J/{psi}K{sup 0}.

Abstract: We report the observation of a new ${D}_{sJ}$ meson produced in ${B}^{+}\ensuremath{\rightarrow}{\overline{D}}^{0}{D}_{sJ}\ensuremath{\rightarrow}{\overline{D}}^{0}{D}^{0}{K}^{+}$. This state has a mass of $M=2708\ifmmode\pm\else\textpm\fi{}{9}_{\ensuremath{-}10}^{+11}\text{ }\text{ }\mathrm{MeV}/{c}^{2}$, a width $\ensuremath{\Gamma}=108\ifmmode\pm\else\textpm\fi{}{23}_{\ensuremath{-}31}^{+36}\text{ }\text{ }\mathrm{MeV}/{c}^{2}$ and a ${1}^{\ensuremath{-}}$ spin-parity. The statistical significance of this observation is $8.4\ensuremath{\sigma}$. The results are based on an analysis of $449\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ events collected at the $\ensuremath{\Upsilon}(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider.

Abstract: We present a measurement of the branching fraction B(D{s}{+}--mu{+}nu{mu}) using a 548 fb{-1} data sample collected by the Belle experiment at the KEKB e{+}e{-} collider. The D{s} momentum is determined by reconstruction of the system recoiling against DKgammaX in events of the type e{+}e{-}--D{s}{*}DKX, D{s}{*}--D{s}gamma, where X represents additional pions or photons from fragmentation. This full-reconstruction method provides high resolution in the neutrino momentum and thus good background separation, equivalent to that achieved by experiments at the tau-charm factories. We obtain the branching fraction B(D{s}{+}--mu{+}nu{mu})=[6.44+/-0.76(stat)+/-0.57(syst)]x10{-3}, implying a D{s} decay constant of f{D{s}}=[275+/-16(stat)+/-12(syst)] MeV.

Abstract: The process e+e-→K+K-J/ψ is observed for the first time via initial-state radiation. The cross section of e+e-→K+K-J/ψ for center-of-mass energies between threshold and 6.0 GeV is measured using 673fb-1 of data collected with the Belle detector on and off the Υ(4S) resonance. No significant signal for Y(4260)→K+K-J/ψ is observed, and we determine B(Y(4260)→K+K-J/ψ)Γ(Y(4260)→e+e-)

Abstract: Nowadays people can store various information in their personal devices because of development and popularization of electronic devices. Though the information can include the valuable contents for others, it remains in the devices unless the users take actions such as "sending." We are doing research on an environment called Urban Memories to distribute the valuable information stored in users' personal devices. In this environment, users exchange their information, such as "bookmark" and "memo," stored in their devices. However, it is difficult for users to retrieve valuable contents from the exchanged information because the exchanged information may be too much. In this paper, we propose a system for users to retrieve the valuable contents from the exchanged information through a map-based interface. This system organizes the exchanged information with three methods each of which focuses on relationship between place-information, person- information and person-place, and visualizes the exchanged information on a map. The system enables users to retrieve the valuable contents from the exchanged information in consideration of relations among person-to-person connection and characteristic of the information with this visualization.

179. The zinc fingers of human poly(ADP-ribose) polymerase are differentially required for the recognition of DNA breaks and nicks and the consequent enzyme activation. Other structures recognize intact DNA

Abstract: The recognition of double-stranded DNA breaks and single-stranded nicks by human poly(ADP-ribose) polymerase and the consequent enzymic activation were examined using derivatives of the enzyme expressed in Escherichia coli. The N-terminal 162 residues encompass two zinc fingers. Deletion or mutation of the first finger results in a loss of activation by DNA with either single-stranded or double-stranded damage. Destruction of the second finger reduces activation by double-stranded DNA breaks only slightly, but eliminates activation by single-stranded DNA nicks. These data suggest that activation by single-stranded DNA nicks requires two zinc fingers, but activation by double-stranded DNA breaks requires only the finger closer to the N terminus. Variant proteins that lack both zinc fingers are enzymically inactive but still exhibit weak DNA binding, which is independent of DNA damage. Thus, other regions are also capable of binding intact DNA, but the recognition of a strand nick or break which occasions the synthesis of poly(ADP-ribose) specifically requires the zinc fingers.

Abstract: Lipid metabolism was examined in patients with hyper- or hypothyroidism. Compared with corresponding age and sex matched controls, serum total cholesterol (T-chol), low density lipoprotein cholesterol (LDL-chol), phospholipid (PL) and LDL levels were significantly low and free fatty acid (FFA) levels were high with apparently normal triglyceride (TG), very low density lipoprotein (VLDL) and high density lipoprotein cholesterol (HDL-chol) levels in 61 hyperthyroid patients, while T-chol, LDL-chol, TG, PL, VLDL and LDL levels were high with normal FFA and HDL-chol levels in 31 hypothyroid patients. Serum lipid levels were then repeatedly measured in 7 men and 7 women with hyperthyroid Graves' disease before treatment (stage I), just after the patients became euthyroid with anti-thyroid drug (stage II) and more than 2 months after the patients remained euthyroid (stage III). Serum T-chol, LDL-chol, PL and LDL levels were low at stage I, significantly elevated at stage II and then normalized at stage III. Transient but significant elevation of serum TG, VLDL and HDL-chol levels at stage II were also observed in men. Accelerated catabolism and anabolism of lipid has been reported in hyperthyroidism. Transient elevation of serum lipid levels suggests a more rapid improvement in catabolism than in anabolism of lipid in an early stage of the medical treatment for hyperthyroidism.

Abstract: We have used the Fermilab 30-in. bubble chamber--hybrid spectrometer to study the rapidities of produced particles'' in the interactions of 200-GeV/{ital c} protons and {pi}{sup +} and {ital K}{sup +} mesons with nuclei of gold, silver, and magnesium. The average rapidity decreases linearly with the number of projectile collisions {nu}{sub {ital p}} (up to {nu}{sub {ital p}}=5) with no {ital A} dependence and little beam dependence. The ratio {ital R} of normalized rapidity distributions for hadron-nucleus to hadron-proton interactions shows a plateau in the central region, and becomes much larger in the target region. However, the increase is significantly less than has been reported in previous experiments. As a function of {nu}{sub {ital p}}, the ratio {ital R} rises linearly in the target region, more gently in the central region, and decreases slowly in the projectile region, in all cases with no {ital A} dependence. Some discrepancies with a previous experiment are observed in the central region. Long-range rapidity correlations are observed in hadron-nucleus events, but not in hadron-proton events. For the former, it is shown that the correlations exist only for those events with multiple projectile collisions, as expected in the multichain dual parton model.

Abstract: A search for the b′ quark via flavour changing neutral current (FCNC) decay modes is described. The search was carried out by looking for isolated high energy photon(s) or back to back jet pairs within 4-jet topologies using the data taken by the TOPAZ detector at TRISTAN in the energy range s=50.0−60.8 GeV. As the FCNC decay branching ratio of the b′ is unknown, the experimental limits are given as a function of mass and branching ratio. Assuming the branching ration of the FCNC mode is 100%, a mass limit for b′ is set ⩾28.3 GeV/c2 independent of Br(b′→bγ).

Abstract: We report the first search for CP violating decays of the $\Upsilon(4S)$ using a data sample that contains 535 million $\Upsilon(4S)$ mesons with the Belle detector at the KEKB asymmetric-energy e^+ e^- collider. A partial reconstruction technique is employed to enhance the signal sensitivity. No significant signals were observed. We obtain an upper limit of $4 \times 10^{-7}$ at the 90 % confidence level for the branching fractions of the $CP$ violating modes, $\Upsilon(4S) \to B^0\bar{B}^0 \to J/\psi K^0_S + J/\psi(\eta_c) K^0_S$. Extrapolating the result, we find that an observation with 5$\sigma$ significance is expected with a 30 ab^{-1} data sample, which is within the reach of a future super B factory.

Abstract: We report a study of the processes e+e- --J/psiD*D[over](*). In J/psiD*D[over]* we observe a significant enhancement in the D*D[over]* invariant mass spectrum, which we interpret as a new charmoniumlike state and denote X(4160). The X(4160) parameters are M=(4156(-20)+25+/-15) MeV/c2 and Gamma=(139(-61)+111+/-21) MeV. We also report a new measurement of the X(3940) mass and width: M=(3942(-6)+7+/-6) MeV/c2 and Gamma=(37(-15)+26+/-8) MeV. The analysis is based on a 693 fb(-1) data sample recorded near the Upsilon(4S) resonance by the Belle detector at the KEKB asymmetric-energy collider.

Abstract: We report the results of a study of neutral B meson decays to the D^0 pi+ pi- final state, where the D^0 is fully reconstructed. The results are obtained from an event sample containing 388 million BB-bar -meson pairs collected in the Belle experiment at the KEKB e^+e^- collider. The total branching fraction of the three-body decay B(bar{B}^0 -> D^0 pi^+ pi^-) =(8.4+-0.4(stat.)+-0.8(syst.)) 10^{-4} has been measured. The intermediate resonant structure of these three-body decays has been studied. From a Dalitz plot analysis we have obtained the product of the branching fractions for D^{*+}_2 and D^{*+}_0 production: B(bar{B}^0-> D^{*+}_2 pi^-) B(D_2^{*+}-> D^{0}\pi^+)= (2.15+-0.17(stat.)+-0.29(syst.)+-0.12(mod.))10^{-4}, and B(bar{B}^0-> D^{*+}_0 pi^-) B(D_0^{*+}-> D^{0} pi^+)= (0.60+-0.13(stat.)}+-0.15(syst.)+-0.22(mod.))10^{-4}. This is the first observation of the bar{B}^0-> D^{*+}_0 pi^- decay. The bar{B^0} -> D^0 rho^0 and D^0f_2 branching fractions are measured to be: B(bar{B}^0->D^0 rho^0)=(3.19+-0.20(stat.)+-0.24(syst.)+-0.38(mod.)) 10^{-4},and B(bar{B}^0-> D^0 f_2)=(1.20+-0.18(stat.)+-0.21(syst.)+-0.32(mod.)) 10^{-4}.

Abstract: The cross section for e+ e- --pi+ pi- psi(2S) between threshold and sqrt[s]=5.5 GeV is measured using 673 fb(-1) of data on and off the Upsilon(4S) resonance collected with the Belle detector at KEKB. Two resonant structures are observed in the pi+ pi- psi(2S) invariant-mass distribution, one at 4361 +/- 9 +/- 9 MeV/c2 with a width of 74 +/- 15 +/- 10 MeV/c2, and another at 4664 +/- 11 +/- 5 MeV/c2 with a width of 48 +/- 15 +/- 3 MeV/c2, if the mass spectrum is parametrized with the coherent sum of two Breit-Wigner functions. These values do not match those of any of the known charmonium states.

Abstract: 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.

Abstract: We present a measurement of $CP$ asymmetry using a time-dependent Dalitz plot analysis of ${B}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}$ decays based on a $414\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ data sample containing $449\ifmmode\times\else\texttimes\fi{}{10}^{6}B\overline{B}$ pairs. The data was collected on the $\ensuremath{\Upsilon}(4S)$ resonance with the Belle detector at the KEKB asymmetric energy ${e}^{+}{e}^{\ensuremath{-}}$ collider. Combining our analysis with information on charged $B$ decay modes, we perform a full Dalitz and isospin analysis and obtain a constraint on the CKM angle ${\ensuremath{\phi}}_{2}$, $68\ifmmode^\circ\else\textdegree\fi{}l{\ensuremath{\phi}}_{2}l95\ifmmode^\circ\else\textdegree\fi{}$ as the 68.3% confidence interval for the ${\ensuremath{\phi}}_{2}$ solution consistent with the standard model (SM). A large SM-disfavored region also remains.

Abstract: We report measurements of the branching fraction and CP violation parameters in B(0)-->D+ D- decays. The results are based on a data sample that contains 535 x 10(6) BB pairs collected at the Upsilon(4S) resonance, with the Belle detector at the KEKB asymmetric-energy e+e- collider. We obtain [1.97+/-0.20(stat) +/- 0.20(syst)] x 10(-4) for the branching fraction of B0-->D+D-. The measured values of the CP violation parameters are S=-1.13+/-0.37+/-0.09, A=0.91+/-0.23+/-0.06, where the first error is statistical and the second is systematic. We find evidence of CP violation in B0-->D+D- at the 4.1sigma confidence level. While the value of S is consistent with expectations from other measurements, the value of the parameter A favors large direct CP violation at the 3.2sigma confidence level, in contradiction to standard model expectations.

Abstract: Using 449 million BBbar pairs collected with the Belle detector at the KEKB asymmetric-energy e^+e^- collider, we observe clear signals for B^+-> \bar{K}^0 K^+ and B^0-> \bar{K}^0 K^0 decays with 5.3 sigma and 6.0 sigma significance, respectively. We measure the branching fractions Br(B^+-> \bar{K}^0 K^+ = (1.22^{+0.32+0.13}_{-0.28-0.16})x10^{-6} and Br(B^0-> \bar{K}^0 K^0) = (0.87^{+0.25}_{-0.20} +- 0.09)x10^{-6}, and partial-rate asymmetries A_{CP}(B^+-> \bar{K}^0 K^+) = 0.13^{+0.23}_{-0.24}+- 0.02 and A_{CP}(B^0-> \bar{K}^0 K^0) = -0.58^{+0.73}_{-0.66}+- 0.04. From a simultaneous fit we also obtain Br(B^+-> K^0��^+)= (22.8^{+0.8}_{-0.7} +- 1.3)x 10^{-6} and A_{CP}(B^+-> K^0 ��^+) = 0.03 +- 0.03 +- 0.01. The first and second error in the branching fractions and the partial-rate asymmetries are statistical and systematic, respectively. No signal is observed for B^0-> K^+ K^- decays, and for this branching fraction we set an upper limit of 4.1x10^{-7} at the 90% confidence level., 6 pages, 3 figures

We find the relative difference of the lifetimes y(CP) to be [1.31+/-0.32(stat)+/-0.25(syst)]%, 3.2 standard deviations from zero. We also search for a CP asymmetry between D(0) and D(0) decays; no evidence for CP violation is found. These results are based on 540 fb(-1) of data recorded by the Belle detector at the KEKB e(+)e(-) collider.

Abstract: We report the first observation of B(0)-->J/psieta decay. These results are obtained from a data sample that contains 449 x10(6) BB[over] pairs accumulated at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We observe a signal with a significance of 8.1 sigma and obtain a branching fraction of (9.5+/-1.7(stat)+/-0.8(syst)) x 10(-6).
