Using the data sample of 711 fb−1 of ϒ(4S) on-resonance data taken by the Belle detector at the KEKB asymmetric-energy electron-positron collider, we present the first measurements of branching fractions of the decays B−→Λ¯c−Ξc′0, B−→Λ¯c−Ξc(2645)0, and B−→Λ¯c−Ξc(2790)0. The signal yields for these decays are extracted from the recoil mass spectrum of the system recoiling against Λ¯c− baryons in selected B− candidates. The branching fraction of B−→Λ¯c−Ξc(2790)0 is measured to be (1.1±0.4±0.2)×10−3, where the first uncertainty is statistical and the second is systematic. The 90% credibility level upper limits on B(B−→Λ¯c−Ξc′0) and B(B−→Λ¯c−Ξc(2645)0) are determined to be 6.5×10−4 and 7.9×10−4, respectively.

Using a data sample of 921.9 fb−1 collected with the Belle detector, we study the process of e+e−→Ds+Ds1(2536)−+c.c. via initial-state radiation. We report the first observation of a vector charmoniumlike state decaying to Ds+Ds1(2536)−+c.c. with a significance of 5.9σ, including systematic uncertainties. The measured mass and width are (4625.9−6.0+6.2(stat)±0.4(syst)) MeV/c2 and (49.8−11.5+13.9(stat)±4.0(syst)) MeV, respectively. The product of the e+e−→Ds+Ds1(2536)−+c.c. cross section and the branching fraction of Ds1(2536)−→D¯*0K− is measured from the DsD¯s1(2536) threshold to 5.59 GeV.

A search for the decays B+→hcK+ and B0→hcKS0 is performed. Evidence for the decay B+→hcK+ is found; its significance is 4.8σ. No evidence is found for B0→hcKS0. The branching fraction for B+→hcK+ is measured to be (3.7−0.9+1.0 −0.8+0.8)×10−5; the upper limit for the B0→hcKS0 branching fraction is 1.4×10−5 at 90% C.L. In addition, a study of the pp¯π+π− invariant mass distribution in the channel B+→(pp¯π+π−)K+ results in the first observation of the decay ηc(2S)→pp¯π+π− with 12.1σ significance. The analysis is based on the 711 fb−1 data sample collected by the Belle detector at the asymmetric-energy e+e− collider KEKB at the ϒ(4S) resonance.

We present the first measurements of branching fractions of rare tau-lepton decays, τ−→π−ντℓ+ℓ− (ℓ=e or μ), using a data sample corresponding to 562 fb−1 collected at a center-of-mass energy of 10.58 GeV with the Belle detector at the KEKB asymmetric-energy e+e− collider. The τ−→π−ντe+e− decay is observed for the first time with 7.0σ significance. The partial branching fraction determined by the structure-dependent mechanisms mediated by either a vector or an axial-vector current for the mass region Mπee>1.05 GeV/c2 is measured to be B(τ−→π−ντe+e−)[Mπ−e+e−>1.05 GeV/c2]=(5.90±0.53±0.85±0.11)×10−6, where the first uncertainty is statistical, the second is systematic, and the third is due to model dependence. In the full phase space, due to the different detection efficiencies for the structure-dependent mechanisms mediated by axial-vector and vector currents, the branching fraction varies from BA(τ−→π−ντe+e−)=(1.46±0.13±0.21)×10−5 to BV(τ−→π−ντe+e−)=(3.01±0.27±0.43)×10−5, respectively. An upper limit is set on the branching fraction of the τ−→π−ντμ+μ− decay, B(τ−→π−ντμ+μ−)<1.14×10−5, at the 90% confidence level.

We report the observation of ϒ(2S)→γηb(1S) decay based on an analysis of the inclusive photon spectrum of 24.7 fb−1 of e+e− collisions at the ϒ(2S) center-of-mass energy collected with the Belle detector at the KEKB asymmetric-energy e+e− collider. We measure a branching fraction of B[ϒ(2S)→γηb(1S)]=(6.1−0.7−0.6+0.6+0.9)×10−4 and derive an ηb(1S) mass of 9394.8−3.1−2.7+2.7+4.5 MeV/c2, where the uncertainties are statistical and systematic, respectively. The significance of our measurement is greater than 7 standard deviations, constituting the first observation of this decay mode.
