Observation of chi_c2 Production in B-meson Decay

open access: yes, 2002
We report the first observation of chi_c2 production in B-meson decays. We find an inclusive B -> chi_c2 X branching fraction of (1.80^{+0.23}_{-0.28}+/- 0.26) 10^-3.

Masses and branching fractions at CDF [PDF]

open access: yesThe European Physical Journal C, 2003
The authors present a collection of new results on b-meson and {Lambda}{sub b} masses and branching fractions measured at CDF. They have improved the measurement of the {Lambda}{sub b} and B{sub s} mass and they have measured the branching fractions of B{sub s} {yields} D{sub s}{pi}, {Lambda}{sub b} {yields} {Lambda}{sub c}{pi} and B{sub u} {yields ...

Study of B^0 -> rho^0 rho^0 decays, implications for the CKM angle phi_2 and search for other B^0 decay modes with a four-pion final state

open access: yes, 2014
We present a study of the branching fraction of the decay B^0->rho0rho0 and the fraction of longitudinally polarized rho0 mesons in this decay. The results are obtained from the final data sample containing 772 million BBbar pairs collected at the Y(4S ...

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

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 ...
