Measurement of the Y(nS) polarizations in pp collisions at √s=7 and 8 TeV
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 ...
Updated branching fraction measurements of B0(s) → K0Sh+h′ − decays
The charmless three-body decays B 0( s) → K0Sh+h′ − (where h(′) = π, K) are analysed using a sample of pp collision data recorded by the LHCb experiment, corresponding to an integrated luminosity of 3 fb−1. The branching ...
Observation of the decay Λ0b → pK − μ + μ − and a search for CP violation
A search for CP violation in the decay Λ0b → pK − μ + μ − is presented. This decay is mediated by flavour-changing neutral-current transitions in the Standard Model and is potentially sensitive to new sources of CP violation. ...
Measurement of the J/ψ pair production cross-section in pp collisions at √s=13 TeV
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
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 ...
Study of the D0 p amplitude in Λ0b → D0 pπ − decays
An amplitude analysis of the decay Λ0b → D0 pπ − is performed in the part of the phase space containing resonances in the D0 p channel. The study is based on a data sample corresponding to an integrated luminosity of 3.0 ...
