Differential branching fractions and isospin asymmetries of B → K (*) μ + μ − decays
The isospin asymmetries of B → Kμ + μ − and B → K * μ + μ − decays and the partial branching fractions of the B 0 → K 0 μ + μ −, B + → K + μ + μ − and B + → K *+ μ + μ − decays are measured as functions of the dimuon mass ...
Observation of B0s →K*∓ K∓ and evidence for B0s →K* −π+ decays
(IOP Publishing, 2014)
Measurements of the branching fractions of B0s→K∗±K∓ and B0s→K∗±π∓ decays are performed using a data sample corresponding to 1.0 fb−1 of proton-proton collision data collected with the LHCb detector at a centre-of-mass ...
Observation of the Λ0b → J/ψ pπ − decay
The first observation of the Cabibbo-suppressed decay Λ 0b → J/ψpπ − is reported using a data sample of proton-proton collisions at 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb−1. A prominent signal is ...
Searches for Λ0b and Ξ0b decays to K0Spπ− and K0SpK− final states with first observation of the Λ0b→K0Spπ− decay
A search for previously unobserved decays of beauty baryons to the final states K0spπ- and K0 spK- is reported. The analysis is based on a data sample corresponding to an integrated luminosity of 1.0 fb- of pp collisions. ...
Study of the kinematic dependences of Λ 0b production in pp collisions and a measurement of the Λ 0b → Λ +c π − branching fraction
The kinematic dependences of the relative production rates, fΛ0b/fd, of Λ 0b baryons and B 0 mesons are measured using Λ 0b → Λ +c π − and B¯0 →D+π− decays. The measurements use proton-proton collision data, corresponding ...
Evidence for the decay B+c→J/ψ3π+2π−
Evidence is presented for the decay B + c → J/ψ3π +2π − using proton-proton collision data, corresponding to an integrated luminosity of 3 fb−1 , collected with the LHCb detector. A signal yield of 32 ± 8 decays is ...
