Measurement of the ratio of B+c branching fractions to J/ψπ+ and J/ψμ+νμ final states
(American Physical Society, 2014-08-27)
The first measurement that relates semileptonic and hadronic decay rates of the B+c meson is performed using proton-proton collision data corresponding to 1.0 fb−1 of integrated luminosity collected ...
Observation of charmonium pairs produced exclusively in pp collisions
(IOPscience, 2014-09)
A search is performed for the central exclusive production of pairs of charmonia produced in proton-proton collisions. Using data corresponding to an
integrated luminosity of 3 fb−1 collected at ...
Measurement of the time-dependent CP asymmetries in B 0s → J/ψK 0S
(Springer, 2015-06-18)
Measurement of ϒ production in pp collisions at √ s = 2.76 TeV
(Springer, 2014-04-29)
The production of Υ(1S), Υ(2S) and Υ(3S) mesons decaying into the dimuon final state is studied with the LHCb detector using a data sample corresponding to an integrated luminosity of 3.3pb−1 collected ...
Study of B− → DK−π+π− and B− → Dπ−π+π− decays and determination of the CKM angle γ
(American Physical Society, 2015-12-17)
We report a study of the suppressed B−→DK−π+π− and favored B−→Dπ−π+π− decays, where the neutral D meson is detected through its decays to the K∓π± and CP -even K+K− and π+π− final states. The measurement ...
Measurement of the fragmentation fraction ratio f s /f d and its dependence on B meson kinematics
(Springer, 2013-04-02)
The relative production rate of B0s and B 0 mesons is determined with the hadronic decays B0s→D−sπ+ and B 0 → D − K +. The measurement uses data corresponding to 1.0 fb−1 of pp collisions at a centre-of-mass ...
Precision measurement of the ratio of the Λb0 to B¯0 lifetimes
(Elsevier, 2014-06-27)
The LHCb measurement of the lifetime ratio of the Λ0b to the B⎯⎯⎯0 meson is updated using data corresponding to an integrated luminosity of 3.0 fb−1 collected using 7 and 8 TeV centre-of-mass energy pp ...
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 ...
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. ...
