  Particle production in two-photon interactions at hadronic collisions is
becoming increasingly relevant in the LHC physics programme as a way to improve
our understanding of the Standard Model and search for signals of New Physics.
A key ingredient for the study of these interactions in $pp$ collisions is the
description of the photon content of the proton, which allow us to derive
predictions for the cross sections associated to events where occur the proton
dissociation (non - exclusive processes) and for those where both incident
protons remain intact (exclusive processes). In this paper, a detailed
comparison of the different models for the elastic and inelastic photon
distributions found in the literature is presented and the current theoretical
uncertainty is estimated. The impact on the invariant mass distribution for the
dimuon production is analyzed. Moreover, the relative contribution of non -
exclusive events is estimated and its dependence on the invariant mass of the
pair is presented. We demonstrate that the predictions for production of pairs
with large invariant mass is strongly dependent on the model assumed to
describe the elastic and inelastic photon distributions and that the ratio
between non - exclusive and exclusive cross sections present a mild energy
dependence. Finally, our results indicate that a future experimental analysis
of the non - exclusive events will be useful to constrain the photon content of
proton.
