Measurement of the properties of the Ξ ∗ 0b baryon
(Springer, 2016)
We perform a search for near-threshold Ξ 0b resonances decaying to Ξ −b π + in a sample of proton-proton collision data corresponding to an integrated luminosity of 3 fb−1 collected by the LHCb experiment. We observe one ...
Observation of Λ0b → ψ(2S)pK− and Λ0b → J/ψπ + π −pK− decays and a measurement of the Λ0b baryon mass
(Springer, 2016)
The decays Λ0b → ψ(2S)pK− and Λ0b → J/ψπ + π −pK− are observed in a data sample corresponding to an integrated luminosity of 3 fb−1, collected in proton-proton collisions at 7 and 8 TeV centre-of-mass energies by the LHCb ...
Central exclusive production of J/ψ and ψ(2S) mesons in pp collisions at √s=13 TeV
(Springer, 2018)
Measurements are reported of the central exclusive production of J/ψ and ψ(2S) mesons in pp collisions at a centre-of-mass energy of 13 TeV. Backgrounds are significantly reduced compared to previous measurements made at ...
Measurement of the exclusive Υ production cross-section in pp collisions at √s=7 TeV and 8 TeV
(Springer, 2015)
A study is presented of central exclusive production of Υ(nS) states, where the Υ(nS) resonances decay to the μ + μ − final state, using pp collision data recorded by the LHCb experiment. The cross-section is measured in ...
Measurement of the B± production cross-section in pp collisions at √s=7 and 13 TeV
(Springer, 2017)
The production of B± mesons is studied in pp collisions at centre-of-mass energies of 7 and 13 TeV, using B± → J/ψ K± decays and data samples corresponding to 1.0 fb−1 and 0.3 fb−1, respectively. The production cross-sections ...
Study of prompt D0 meson production in pPb collisions at √sNN=5 TeV
(Springer, 2017)
Production of prompt D0 mesons is studied in proton-lead and lead-proton collisions recorded at the LHCb detector at the LHC. The data sample corresponds to an integrated luminosity of 1.58±0.02 nb−1 recorded at a ...
Measurement of the Y(nS) polarizations in pp collisions at √s=7 and 8 TeV
(Springer, 2017)
The polarization of the Y(1S), Y(2S) and Y(3S) mesons, produced in pp collisions at centre-of-mass energies √s=7 and 8 TeV, is measured using data samples collected by the LHCb experiment, corresponding to integrated ...
Observation of Z production in proton-lead collisions at LHCb
(Springer, 2014)
The first observation of Z boson production in proton-lead collisions at a centre-of-mass energy per proton-nucleon pair of √sNN= 5 TeV is presented. The data sample corresponds to an integrated luminosity of 1.6 nb−1 ...
Measurement of the J/ψ pair production cross-section in pp collisions at √s=13 TeV
(Springer, 2017)
The production cross-section of J/ψ pairs is measured using a data sample of pp collisions collected by the LHCb experiment at a centre-of-mass energy of √s=13 TeV, corresponding to an integrated luminosity of 279 ±11 pb−1. ...
Study of bb¯correlations in high energy proton-proton collisions
(Springer, 2017)
Kinematic correlations for pairs of beauty hadrons, produced in high energy proton-proton collisions, are studied. The data sample used was collected with the LHCb experiment at centre-of-mass energies of 7 and 8 TeV and ...
