Semiexclusive production of vector mesons in proton-proton collisions with electromagnetic dissociation of protons

Abstract

We discuss the semiexclusive production of vector mesons in protonproton collisions with electromagnetic dissociation of one of the protons. Several differential distribution in missing mass (MX), or single-particle variables related exclusively to the produced vector meson are calculated for pp center-of-mass energies 7 and 13 TeV. The cross sections and some differential distributions are compared to their counterparts for purely exclusive reaction pp→pV p$pp \to pV{\rm{ }}p$. For electromagnetic dissociation the important property is that the pγ⋆→Xp$p\gamma^{\bigstar} \to Xp$ transitions are given by the electromagnetic structure function of proton. In our calculations we use different parametrizations of the structure function and discuss how it is constrained by the data on virtual photoabsorption on a proton.
