Central exclusive production of J/ψ and ψ(2S) mesons in pp collisions at √s=13 TeV
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
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 ...
Observation of Z production in proton-lead collisions at LHCb
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 ...
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 ...
Observation of associated production of a Z boson with a D meson in the forward region
A search for associated production of a Z boson with an open charm meson is presented using a data sample, corresponding to an integrated luminosity of 1.0 fb−1 of proton-proton collisions at a centre-of-mass energy of ...
