Measurement of the Ξ−b and Ω−b baryon lifetimes
(Elsevier, 2014-09-07)
Using a data sample of pp collisions corresponding to an integrated luminosity of 3 fb−1, the Ξ−b and Ω−b baryons are reconstructed in the Ξ−b→J/ψΞ− and Ω−b→J/ψΩ− decay modes and their lifetimes measured ...
Study of B0s → J/ψπ+π−K+K− decays
(Springer, 2021-02)
The decays B0s → J/ψπ+π−K+K− are studied using a data set corresponding to an integrated luminosity of 9 fb−1, collected with the LHCb detector in proton-proton collisions at centre-of-mass energies of ...
Identification of beauty and charm quark jets at LHCb
(IOPscience, 2015-06)
Identification of jets originating from beauty and charm quarks is important for measuring Standard Model processes and for searching for new physics. The performance of algorithms developed to select ...
Measurement of ψ(2S) production cross-sections in proton-proton collisions at s√=7 and 13 TeV
(Springer, 2020-02)
The cross-sections of ψ(2S) meson production in proton-proton collisions at s√=13 TeV are measured with a data sample collected by the LHCb detector corresponding to an integrated luminosity of 275 pb−1. ...
Observation of the decay B+c → J/ψ K + K − π +
(Springer, 2013-11-12)
The decay B+c → J/ψK + K − π + is observed for the first time, using protonproton collisions collected with the LHCb detector corresponding to an integrated luminosity of 3 fb−1. A signal yield of 78 ± ...

Measurement of the CP-violating phase φsin B0s→J/ψπ+π−decays
(Elsevier, 2014-09)
The mixing-induced CP-violating phase in and decays is measured using the final state in data, taken from 3 fb−1 of integrated luminosity, collected with the LHCb detector in 7 and 8 TeV centre-of-mass ...
Measurement of CP asymmetry in B 0 s → D ∓ s K ± decays
(Springer, 2014-11-13)
We report on measurements of the time-dependent CP violating observables in B 0 s → D ∓ s K ± decays using a dataset corresponding to 1.0 fb−1 of pp collisions recorded with the LHCb detector. We find ...

Measurement of b-hadron branching fractions fortwo-body decays into charmless charged hadrons
(Springer, 2012-10-04)
Based on data corresponding to an integrated luminosity of 0.37 fb−1 collected by the LHCb experiment in 2011, the following ratios of branching fractions are measured:
