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 32.6nb-1. Differential cross sections as functions of the Υ (nS) transverse momentum squared pT2, and rapidity y, are presented. The Υ (1 S) 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<826GeV. The data are compared to theoretical predictions based on perturbative quantum chromodynamics and to previous measurements. © 2019, CERN for the benefit of the CMS collaboration.Springer Nature2019Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/13792https://doi.org/10.1140/epjc/s10052-019-6774-81434-6044enEuropean Physical Journal Cinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/13792
