Differential cross sections as functions of the nS) transverse momentum squared and rapidity y, are presented. The 1S) photoproduction cross section is extracted in the rapidity range < 2.2, which corresponds to photon-proton centre-of-mass energies in the range 91 W < 826 GeV. The data are compared to theoretical predictions based on perturbative quantum chromodynamics and to previous measurements.eninfo:eu-repo/semantics/openAccessCMSUPCphotoproductionYpPbArticle10.1140/epjc/s10052-019-6774-831007586Q1WOS:000462673300003
