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 NRQCD27 p.application/pdfengcc-by (c) Alfonso Albero, Alejandro et al., 2021https://creativecommons.org/licenses/by/4.0/HadronsGran Col·lisionador d'HadronsFísica de partículesExperimentsHadronsLarge Hadron Collider (France and Switzerland)Particle physicsExperimentsinfo:eu-repo/semantics/article7210822022-05-10info:eu-repo/semantics/openAccess
