Measurement of ψ(2S) polarisation in pp collisions at √s=7 TeV
(Springer, 2014)
The polarisation of prompt ψ(2S) mesons is measured by performing an angular analysis of ψ(2S)→μ+μ− decays using proton-proton collision data, corresponding to an integrated luminosity of 1.0 fb −1, collected by the LHCb ...
Search for the lepton flavour violating decay τ − → μ − μ + μ −
(Springer, 2015)
A search for the lepton flavour violating decay τ − → μ − μ + μ − is performed with the LHCb experiment. The data sample corresponds to an integrated luminosity of 1.0 fb−1 of proton-proton collisions at a centre-of-mass ...
Search for the Λ 0b → Λη ′ and Λ 0b → Λη decays with the LHCb detector
(Springer, 2015)
A search is performed for the as yet unobserved baryonic Λ 0b → Λη ′ and Λ 0b → Λη decays with 3 fb−1 of proton-proton collision data recorded by the LHCb experiment. The B0 → K 0sη ′ decay is used as a normalisation ...
Study of the rare B0s and B0s decays into the π+π−μ+μ−final state
(Elsevier, 2015)
A search for the rare decays B0s→π+π−μ+μ−and B0→π+π−μ+μ−is performed in a data set corresponding to an integrated luminosity of 3.0fb−1collected by the LHCb detector in proton–proton collisions at centre-of-mass energies ...
Measurement of the B+c meson lifetime using B+c→J/ψμ+νμX decays
(Springer, 2014)
The lifetime of the B+c meson is measured using semileptonic decays having a J/ψ meson and a muon in the final state. The data, corresponding to an integrated luminosity of 2 fb −1, are collected by the LHCb detector in ...
Study of Υ production and cold nuclear matter effects in pPb collisions at √sNN = 5 TeV
(Springer, 2014)
Production of Υ mesons in proton-lead collisions at a nucleon-nucleon centre-of-mass energy √sNN = 5 TeV is studied with the LHCb detector. The analysis is based on a data sample corresponding to an integrated luminosity ...
Study of the kinematic dependences of Λ 0b production in pp collisions and a measurement of the Λ 0b → Λ +c π − branching fraction
(Springer, 2014)
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 ...
Search for the decay D0→π+π−μ+μ−

A search for the D0→π+π−μ+μ− decay, where the muon pair does not originate from a resonance, is
performed using proton–proton collision data corresponding to an integrated luminosity of 1.0 fb−1
recorded by the LHCb ...
Measurement of the CKM angle γ using B± → DK± with D → K0Sπ+π−, K0SK+K− decays
(Springer, 2018)
A binned Dalitz plot analysis of B± → DK± decays, with D → K 0Sπ+π− and D → K 0SK+K−, is used to perform a measurement of the CP-violating observables x± and y±, which are sensitive to the Cabibbo-Kobayashi-Maskawa angle ...
