Measurement of charged particle multiplicities and densities in pp collisions at √s=7 TeV in the forward region
(Springer, 2014)
Charged particle multiplicities are studied in proton–proton collisions in the forward region at a centre-of-mass energy of √s=7TeV with data collected by the LHCb detector. The forward spectrometer allows access to a ...
Measurement of the inelastic pp cross-section at a centre-of-mass energy of √s = 7 TeV
(Springer, 2015)
The cross-section for inelastic proton-proton collisions, with at least one prompt long-lived charged particle of transverse momentum p T > 0.2GeV/c in the pseudorapidity range 2.0 < η < 4.5, is measured by the LHCb ...
Study of J/ψ production and cold nuclear matter effects in pPb collisions at √sNN = 5 TeV
(Springer, 2014)
The production of J/ψ mesons with rapidity 1.5 < y < 4.0 or −5.0 < y < −2.5 and transverse momentum p T < 14 GeV/c is studied with the LHCb detector in proton-lead collisions at a nucleon-nucleon centre-of-mass energy √sNN ...
Measurement of the B 0s → ϕϕ branching fraction and search for the decay B 0 → ϕϕ
(Springer, 2015)
Using a dataset corresponding to an integrated luminosity of 3.0 fb−1 collected in pp collisions at centre-of-mass energies of 7 and 8 TeV, the B 0s → ϕϕ branching fraction is measured to be
B(B0s→ϕϕ)=(1.84±0.05(stat ...
Searches for Λ0b and Ξ0b decays to K0Spπ− and K0SpK− final states with first observation of the Λ0b→K0Spπ− decay
(Springer, 2014)
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. ...
Search for CP violation using T-odd correlations in D 0 → K + K −π+π− decays
(Springer, 2014)
A search for CP violation using T-odd correlations is performed using the four-body D 0 → K + K −π+π− decay, selected from semileptonic B decays. The data sample corresponds to integrated luminosities of 1.0 fb−1 and 2.0 ...

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 ...
