Inclusive Photoproduction of Υ(1s) and J/ψ in Ultra-peripheral p-Pb Collisions at s^(1/2) = 5.5 TeV

摘要

With a photon spectrum of high energy charged partons, both differential and total cross sections of J/ψ√andΥ(1s) inclusive photoproduction in ultra-peripheral p-Pb Collisions (UPCs) at s=5.5 Te V are given. A direct photon process and a resolved photon process including fragment and non-fragment contributions are considered. The total cross section is compared to the inelastic production results in coherent p-Pb collisions at the same center-of-mass energy. Our results seem non-negligible.
