Аннотация: The production cross-sections of Υ(1S), Υ(2S) and Υ(3S) mesons in proton-proton collisions at s√= 13 TeV are measured with a data sample corresponding to an integrated luminosity of 277±11 pb−1 recorded by the LHCb experiment in 2015. The Υ mesons are reconstructed in the decay mode Υ→μ+μ−. The differential production cross-sections times the dimuon branching fractions are measured as a function of the Υ transverse momentum, pT, and rapidity, y, over the range 0<pT<30 GeV/c and 2.0<y<4.5. The ratios of the cross-sections with respect to the LHCb measurement at s√= 8 TeV are also determined. The measurements are compared with theoretical predictions based on NRQCD.
