| 330 | _aThe exclusive photoproduction of Υ(nS)Υ(nS) meson states from protons, γp→Υ(nS)pγp→Υ(nS)p (with n=1,2,3n=1,2,3), is studied in ultraperipheral ppPb collisions at a centre-of-mass energy per nucleon pair of sNN−−−√=5.02TeVsNN=5.02TeV. The measurement is performed using the Υ(nS)→μ+μ−Υ(nS)→μ+μ− decay mode, with data collected by the CMS experiment corresponding to an integrated luminosity of 32.6nb−1nb−1. Differential cross sections as functions of the Υ(nS)Υ(nS) transverse momentum squared p2TpT2, and rapidity y, are presented. The Υ(1S)Υ(1S) photoproduction cross section is extracted in the rapidity range |y|<2.2|y|<2.2, which corresponds to photon-proton centre-of-mass energies in the range 91<Wγp<826GeV91<Wγp<826GeV. The data are compared to theoretical predictions based on perturbative quantum chromodynamics and to previous measurements. | ||
