| Özet |
| The exclusive photoproduction of Υ (nS) meson states from protons, γp→ Υ (nS) p (with n= 1, 2, 3), is studied in ultraperipheral pPb collisions at a centre-of-mass energy per nucleon pair of sNN−−−√= 5.02 TeV. The measurement is performed using the Υ (nS)→ μ+ μ− decay mode, with data collected by the CMS experiment corresponding to an integrated luminosity of 32.6 nb− 1. Differential cross sections as functions of the Υ (nS) transverse momentum squared p2T, and rapidity y, are presented. The Υ (1S) photoproduction cross section is extracted in the rapidity range| y|< 2.2, which corresponds to photon-proton centre-of-mass energies in the range 91< Wγp< 826 GeV. The data are compared to theoretical predictions based on perturbative quantum chromodynamics and to previous measurements. |
