We discuss the semi-exclusive production of vector mesons in proton– proton 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 the pp center-of-mass energies of 7 and 13 TeV. The cross sections and some differential distributions are compared to their counterparts for purely exclusive reaction pp → pV p. For electromagnetic dissociation, the important property is that the pγ → 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.
