Abstract

We perform the first search for lepton-number-violating B +?D-+?+ decays, where and ? stand for e or ?, using 772�106 BB? pairs accumulated at the ?(4S) resonance with the Belle detector at the KEKB e+e- collider. No evidence for these decays has been found. Assuming uniform three-body phase space distributions for the D-+?+ decays, we set the following upper limits on the branching fractions at 90% confidence level: B(B+?D-e+e+)

Abstract

We present results from a study of X(3872)???J/? decays produced via exclusive B?KX(3872) decays. We determine the mass to be MX(3872)=(3871.85�0.27(stat)�0.19(syst))MeV, a 90% confidence level upper limit on the natural width of ? X(3872)X(3872)=(-0.71�0.96(stat)�0.19(syst)) MeV. A search for a charged partner of the X(3872) in the decays B ?0?K-X+ or B+? K0X+, X+??+?0J/? resulted in upper limits on the product branching fractions for these processes that are well below expectations for the case that the X(3872) is the neutral member of an isospin triplet. In addition, we examine possible JPC quantum number assignments for the X(3872) based on comparisons of angular correlations between final state particles in X(3872)??+?-J/? decays with simulated data for JPC values of 1++ and 2 -+. We examine the influence of ?-? interference in the M(?+?-) spectrum. The analysis is based on a 711fb-1 data sample that contains 772�106 BB? meson pairs collected at the ?(4S) resonance in the Belle detector at the KEKB e +e- collider. � 2011 American Physical Society.

Abstract

We report the first observation of the radiative decay B0?� K0? using a data sample of 772�106 BB? pairs collected at the ?(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We observe a signal of 37�8 events with a significance of 5.4 standard deviations including systematic uncertainties. The measured branching fraction is B(B0?�K0?)= (2.74�0.60�0.32)�10-6, where the uncertainties are statistical and systematic, respectively. We also report the first measurements of time-dependent CP-violation parameters: S �KS0?=+0.74-1.05+0.72(stat)-0.24+0.10(syst) and A �KS0?=+0.35�0.58(stat)-0.10+0.23(syst). Furthermore, we measure B(B+?�K+?)=(2. 48�0.30�0.24)�10-6, ACP=-0. 03�0.11�0.08, and find that the signal is concentrated in the M�K mass region near threshold. � 2011 American Physical Society.

Abstract

We report the first observation of the doubly Cabibbo-suppressed decays D+?K+?(?) using a 791fb-1 data sample collected with the Belle detector at the KEKB asymmetric-energy e +e- collider. The ratio of the branching fractions of doubly Cabibbo-suppressed relative to singly Cabibbo-suppressed D +??+?(?) decays are B(D +?K+?)/B(D+??+? )=(3.06�0.43�0.14)% and B(D+?K+? ?)/B(D+??+? ?)=(3.77�0.39�0.10)%. From these, we find that the relative final-state phase difference between the tree and annihilation amplitudes in D+ decays, ?TA, is (72�9)�or (288�9)�. We also report the most precise measurements of CP asymmetries to date: ACPD+?? +?=(+1.74�1.13�0.19)% and ACPD+? ?+??=(-0.12�1.12�0.17)%. � 2011 American Physical Society.

Abstract

We report a high-statistics measurement of the relative branching fraction B(D0→π+π−π0)/B(D0→K−π+π0) using a 532 fb−1 data sample collected with the Belle detector at the KEKB asymmetric-energy e+e− collider. The measured value of the relative branching fraction is B(D0→π+π−π0)/B(D0→K−π+π0)=(10.12±0.04(stat)±0.18(syst))×10−2, which has an accuracy comparable to the world average. We also present a measurement of the time-integrated CP asymmetry in D0→π+π−π0 decay. The result, ACP=(0.43±1.30)%, shows no significant CP violation.

Abstract

The cross sections for the reactions e+e−→ϕη, ϕη′, ρη, ρη′ have been measured using a data sample of 516 fb−1 collected with the Belle detector at the KEKB asymmetric-energy e+e− collider. The corresponding values of the cross sections are: 1.4±0.4±0.1 fb (ϕη), 5.3±1.1±0.4 fb (ϕη′), 3.1±0.5±0.1 fb (ρη) and 3.3±0.6±0.2 fb (ρη′). The energy dependence of the cross sections is presented using Belle measurements together with those of CLEO and BaBar.

Abstract

We have searched for neutrinoless τ lepton decays into ℓ and V0, where ℓ stands for an electron or muon, and V0 for a vector meson (ϕ, ω, K∗0, K¯∗0 or ρ0), using 543 fb−1 of data collected with the Belle detector at the KEKB asymmetric-energy e+e− collider. No excess of signal events over the expected background has been observed, and we set upper limits on the branching fractions in the range (5.9–18)×10−8 at the 90% confidence level. These upper limits are significantly more restrictive than our previous results for the ℓϕ, ℓK∗0, ℓK¯∗0 and ℓρ0 modes.

19. Inhibition of Δ5-3β hydroxysteroid dehydrogenase activity in pre-implantation mouse embryos and their implantation by sheep ovarian follicular fluid peptide

Author

Joshi, N.J., Moodbidri, S. B., and Nandedkar, Tarala D.

Abstract

Abstract. The activity of Δ5-3β hydroxysteroid dehydrogenase (Δ5-3β HSD) in pre-implantation mouse embryos was inhibited following their prior incubation with partially purified sheep ovarian follicular fluid peptide (OFFP). OFFP, 5 μl, injected into the uterine lumen of day 4 pregnant mice impaired the ensuing implantation of embryos. Our observations suggest that OFFP may inhibit steroid metabolizing activity in pre-implantation embryos and thereby interfere with the process of implantation.

Abstract

We have searched for neutrinoless τ lepton decays into ℓ and V0, where ℓ stands for an electron or muon, and V0 for a vector meson (φ{symbol}, ω, K* 0, over(K, ̄)* 0 or ρ0), using 543 fb-1 of data collected with the Belle detector at the KEKB asymmetric-energy e+ e- collider. No excess of signal events over the expected background has been observed, and we set upper limits on the branching fractions in the range (5.9 - 18) × 10-8 at the 90% confidence level. These upper limits are significantly more restrictive than our previous results for the ℓφ{symbol}, ℓ K* 0, ℓ over(K, ̄)* 0 and ℓ ρ0 modes. © 2008 Elsevier B.V.

Abstract

We report measurements of charmless hadronic B0 decays into the π+π-K+π- final state. The analysis uses a sample of 657×106 BB̄ pairs collected with the Belle detector at the KEKB asymmetric-energy e+e- collider at the resonance. The decay B0→ρ0K+π- is observed for the first time; the significance is 5.0σ and the corresponding partial branching fraction for MKπ(0.75,1.20)GeV/c2 is [2.8±0.5(stat) ±0.5(syst)]×10-6. We also obtain the first evidence for B0→f0(980)K+π- with 3.5σ significance and for B0→π+π- K*0 with 4.5σ significance. For the two-body decays B0→ρ0K*0 and B0→f0(980)K*0, the significances are 2.7σ and 2.5σ, respectively, and the upper limits on the branching fractions are 3.4×10-6 and 2.2×10-6 at 90% confidence level. © 2009 The American Physical Society.

Abstract

We have studied Bs0→Ds-π+ and Bs0→Ds K± decays using 23.6fb-1 of data collected at the Υ(5S) resonance with the Belle detector at the KEKB e+e- collider. This highly pure Bs0→Ds-π+ sample is used to measure the branching fraction, B(Bs0→Ds-π+)=[3.67-0.33+0.35(stat)-0. 42+0.43(syst)±0.49(fs)]×10-3 (fs=NBs(*)B̄s(*)/ Nbb̄) and the fractions of Bs0 event types at the Υ(5S) energy, in particular NBs*B̄s*/NBs(*)B̄s(*)=(90.1-4.0+3. 8±0.2)%. We also determine the masses M(Bs0)=(5364.4±1.3±0. 7)MeV/c2 and M(Bs*)=(5416.4±0.4±0.5)MeV/c2. In addition, we observe Bs0→Ds K± decays with a significance of 3.5σ and measure B(Bs0→Ds K±)=[2.4-1.0+1.2(stat)±0.3(syst)±0. 3(fs)]×10-4. © 2009 The American Physical Society.

Abstract

We present a study of B→X(3872)K with X(3872) decaying to D*0D̄0 using a sample of 657×106 BB̄ pairs recorded at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. Both D*0→D0γ and D*0→D0π0 decay modes are used. We find a peak of 50.1-11.1+14.8 events with a mass of (3872.9-0.4-0.5+0.6+0.4)MeV/c2, a width of (3.9-1.4-1.1+2.8+0.2)MeV/c2 and a product branching fraction B(B→X(3872)K)×B(X(3872)→D*0D̄0)=(0. 80±0.20±0.10)×10-4, where the first errors are statistical and the second ones are systematic. The significance of the signal is 6.4σ. The difference between the fitted mass and the D*0D̄0 threshold is calculated to be (1.1-0.4-0.3+0.6+0.1)MeV/c2. We also obtain an upper limit on the product of branching fractions B(B→Y(3940)K) ×B(Y(3940)→D*0D̄0) of 0.67×10 -4 at 90% CL. © 2010 The American Physical Society.

Abstract

From a Dalitz plot analysis of B→Kπ+ψ′ decays, we find a signal for Z(4430)+→π+ψ′ with a mass M=(4443-12-13+15+19)MeV/ c2, width Γ=(107-43-56+86+74)MeV, product branching fraction B(B̄0→K-Z(4430)+)×B(Z(4430)+→π+ψ′)=(3.2-0.9-1. 6+1.8+5.3)×10-5, and significance of 6.4σ that agrees with previous Belle measurements based on the same data sample. In addition, we determine the branching fraction B(B0→K*(892)0ψ′)=(5.52-0.32-0.58+0.35+0. 53)×10-4 and the fraction of K*(892)0 mesons that are longitudinally polarized fL=(44.8-2.7-5.3+4.0+4.0)%. These results are obtained from a 605fb-1 data sample that contains 657×106 BB̄ pairs collected near the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. © 2009 The American Physical Society.

Abstract

We present a search for the rare decays B→h(*)νν̄, where h(*) stands for a light meson. A data sample of 535×106 BB̄ pairs collected with the Belle detector at the KEKB e+e- collider is used. Signal candidates are required to have an accompanying B meson fully reconstructed in a hadronic mode and signal side particles consistent with a single h(*) meson. No significant signal is observed and we set upper limits on the branching fractions at 90% confidence level. The limits on B0→K*0νν̄ and B+→K+νν̄ decays are more stringent than the previous constraints, while the first searches for B0→K0νν̄, π0νν̄, ρ0νν̄, νν̄ and B+→K*+νν̄, ρ+νν̄ are reported. © 2007 The American Physical Society.

Abstract

First observations of the Bs0→Ds*-π+, Bs0→Ds-ρ+ and Bs0→Ds*-ρ+ decays are reported together with measurements of their branching fractions: B(Bs0→Ds*-π+)=[2.4-0.4+0.5(stat)±0.3(syst) ±0.4(fs)]×10-3, B(Bs0→Ds-ρ+)=[8.5-1. 2+1.3(stat)±1.1(syst)±1.3(fs)]×10-3 and B(Bs0→Ds*-ρ+)=[11.9-2.0+2.2(stat)±1.7(syst) ±1.8(fs)]×10-3 (fs=NBs(*)B̄s(*)/ Nbb̄). From helicity-angle distributions, we measured the longitudinal polarization fraction in Bs0→Ds*-ρ+ decays to be fL(Bs0→Ds*-ρ+)=1.05-0.10+0.08(stat)-0.04+0.03(syst). These results are based on a 23.6fb-1 data sample collected at the Υ(5S) resonance with the Belle detector at the KEKB e+e - collider. © 2010 The American Physical Society.

Abstract

The cross sections for the reactions e+ e- → φ{symbol} η, φ{symbol} η′, ρη, ρ η′ have been measured using a data sample of 516 fb- 1 collected with the Belle detector at the KEKB asymmetric-energy e+ e- collider. The corresponding values of the cross sections are: 1.4 ± 0.4 ± 0.1 fb (φ{symbol} η), 5.3 ± 1.1 ± 0.4 fb (φ{symbol} η′), 3.1 ± 0.5 ± 0.1 fb (ρ η) and 3.3 ± 0.6 ± 0.2 fb (ρ η′). The energy dependence of the cross sections is presented using Belle measurements together with those of CLEO and BaBar. © 2009 Elsevier B.V.

Abstract

We present a study of B0→Ds*+π- and B0→Ds*-K+ decays based on a sample of 657×106 BB̄ events collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. We measure the branching fractions to be B(B0→Ds*+π-)=(1.75±0.34(stat)±0.17(syst) ±0.11(B))×10-5 and B(B0→Ds*-K +)=(2.02±0.33(stat)±0.18(syst)±0.13(B)) ×10-5, with significances of 6.1 and 8.0 standard deviations, respectively. The first uncertainty is statistical, the second is due to the experimental systematics, and the third is from uncertainties in the Ds+ decay branching fractions. From our measurements, we obtain the most precise determination so far of RD*π, where RD*π is the ratio between amplitudes of the doubly Cabibbo-suppressed decay B0→D*+π- and the Cabibbo-favored B0→D*-π+ decay. © 2010 The American Physical Society.

Abstract

We report the first measurement of time-dependent CP asymmetry in B0→KS0ρ0γ decays based on 657×106 BB̄ pairs collected with the Belle detector at the KEKB asymmetric-energy collider. We measure the CP-violating parameter SKS0ρ0γ=0.11±0.33(stat)-0.09+0.05(syst) from a signal of 212±17 events. We also obtain the effective direct CP-violating parameter Aeff=0.05±0.18(stat)±0.06(syst) for mKS0π+π

Abstract

We report the first observation of B±→ψ(2S)π±, a Cabibbo- and color-suppressed decay. This analysis is based on 657×106 BB̄ events collected at the Υ(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. The measured branching fraction is (2.44±0.22±0.20)×10-5 and the charge asymmetry is A=0.022±0.085±0.016. The ratio of the branching fractions B(B±→ψ(2S)π±)/B(B±→ψ(2S)K±)=(3. 99±0.36±0.17)% is also determined. © 2008 The American Physical Society.
