Measurement of the absolute branching fraction of the inclusive decay $$\Lambda _c^+ \rightarrow K_S^0X$$ Λ c + → K S 0 X

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We report the first measurement of the absolute branching fraction of the inclusive decay $$\Lambda _c^+ \rightarrow K_S^0X$$ Λ c + → K S 0 X . The analysis is performed using an $$e^+e^-$$ e + e - collision data sample corresponding to an integrated ...

Measurement of the branching fractions of psi(2S) -> 3(pi+pi-) and J/psi -> 2(pi+pi-)

open access: yes, 2005
Using data samples collected at sqrt(s) = 3.686GeV and 3.650GeV by the BESII detector at the BEPC, the branching fraction of psi(2S) -> 3(pi+pi-) is measured to be [4.83 +- 0.38(stat) +- 0.69(syst)] x 10^-4, and the relative branching fraction of J/psi ->

First observation of B + → D s + K + K − decays and a search for B + → D s + ϕ decays

open access: yesJournal of High Energy Physics, 2018
A search for B + → D s + K + K − decays is performed using pp collision data corresponding to an integrated luminosity of 4.8 fb−1, collected at centre-of-mass energies of 7, 8 and 13 TeV with the LHCb experiment. A significant signal is observed for the

Dalitz analysis of B --> K pi psi' decays and the Z(4430)+

open access: yes, 2009
From a Dalitz plot analysis of B --> K pi psi' decays, we find a signal for Z(4430)+ --> pi+ psi' with a mass M= (4443(+15-12)(+19-13))MeV/c^2, width Gamma= (107(+86-43)(+74-56))MeV, product branching fraction BR(B0 --> K- Z(4430)+) x BR(Z(4430)+ --> pi+

Contributions of vector leptoquark to Ξb→Ξcτν¯τ decay

open access: yesNuclear Physics B, 2019
Motivated by the RD(⁎) anomalies in semileptonic B meson decay which can be explained by adding a single vector leptoquark U3(3,3,23) to the Standard Model, we further analyse the New Physics effects of vector leptoquark to the heavy baryon Ξb→Ξcτ−ν¯τ ...

Annihilation-Type Semileptonic B-Meson Decays

open access: yesEPJ Web of Conferences, 2017
The rare semileptonic decay B0 → ϕℓ+ℓ−, where ℓ is an electron or muon, is considered in the QCD Factorization approach. The differential branching fraction, partially integrated over the interval q2 = [1 GeV2, 8 GeV2] of dilepton invariant mass squared,
