چکیده
A baryonic decay of the B(c)(+) meson, B(c)(+) → J/ψppπ(+), is observed for the first time, with a significance of 7.3 standard deviations, in pp collision data collected with the LHCb detector and corresponding to an integrated luminosity of 3.0 fb(-1) taken at center-of-mass energies of 7 and 8 TeV. With the B(c)(+) → J/ψπ(+) decay as the normalization channel, the ratio of branching fractions is measured to be B(B(c)(+) → J/ψppπ(+))/B(B(c)(+) → J/ψπ(+)) = 0.143(-0.034)(+0.039)(stat) ± 0.013(syst). The mass of the B(c)(+) meson is determined as M(B(c)(+) = 6274.0 ± 1.8(stat) ± 0.4(syst) MeV/c(2), using the B(c)(+) → J/ψppπ(+) channel.

Status of baryonic B decays
An overview of exclusive two-body and three-body baryonic B decays is given. The threshold enhancement effect in the dibaryon invariant mass and the angular distributions in the dibaryon rest frame are stressed and explained. Weak radiative baryonic B decays mediated by the electromagnetic penguin process b → sγ are discussed. Apart from the first observation of the radiative penguin decay B− →...
متن کاملEffects of final state interaction in B^+_c to D^0 K^+ decay
In this paper, the decay of Bc+ meson, which consists of two b and c heavy quarks, into the Do and K+ mesons was studied. Given that the experimental branching ratio for this decay was within the range of 3.75*10-5 to 11.16*10-5; it was decided to calculate the theoretical branching ratio by applying the final state interaction (FSI) through the T and cross-section channels. In this process, b...

We analyze the radiative leptonic Bc decay mode: Bc → lνγ (l = e, μ) using a QCD-inspired constituent quark model. The prediction: B(Bc → lνγ) ≃ 7 × 10 makes this channel experimentally promising in view of the large number of Bc mesons which are expected to be produced at the future hadron facilities.

متن کاملRare B Decays at Belle
Recent results of rare B decay analyses based on 31.9 million BB̄ collected with the Belle detector at the KEKB asymmetric ee collider are presented. We have made the first observation of charmless baryonic decay B → ppK, the three-body B → Kππ and B → KKK. The measured branching fractions are B(B → pp̄K) = (4.3 −0.9 ± 0.5) × 10 , B(B→Kππ) = (53.2 ± 11.3 ± 9.7) × 10, and B(B→KKK) = (34.8 ± 6.7 ± ...
