Evidence for BS0 meson production in Z0 decays

Observation of Bs0→K*±K∓ and evidence for Bs0→K*−π+ decays

Measurements of the branching fractions of → ± ∓ B K K * s and π → ± ∓ B K* s decays are performed using a data sample corresponding to − 1.0 fb 1 of protonproton collision data collected with the LHCb detector at a centre-of-mass energy of 7 TeV, where the ± K* mesons are reconstructed in the π± KS final state. The first observation of the → ± ∓ B K K * s decay and the first evidence for the π...

Schlatter The Bs –B 0 s oscillation frequency ms is measured with 36 pb −1 of data collected in pp collisions at √ s = 7 TeV by the LHCb experiment at the Large Hadron Collider. A total of 1381 Bs → D−s π+ and Bs → D−s π+π−π+ signal decays...

P-wave charmonium production in B-meson decays.

We calculate the decay rates of B mesons into P-wave charmonium states using new factorization formulas that are valid to leading order in the relative velocity of the charmed quark and antiquark and to all orders in the running coupling constant of QCD. We express the production rates for all four P states in terms of two nonperturbative parameters, the derivative of the wavefunction at the or...

Axial Anomaly Effects in Pion and Z0 Radiative Decays

We discuss a connection between axial anomaly and polarized radiative processes. By comparison with the corresponding unpolarized cases, we consider some physical outputs for the π+ and Z0 polarized radiative decays. We analyse in detail the pattern of mass singularity cancellation. PACS 11.30.Rd, 13.20.Cz, 11.15.Bt
