91. gamma-UPC: Automated generation of exclusive photon-photon processes in ultraperipheral proton and nuclear collisions

Photon-photon physics and hard diffraction

The automated generation of arbitrary exclusive final states produced via photon fusion in ultraperipheral high-energy collisions of protons and/or nuclei is implemented in the MadGraph5_aMC@NLO and HelacOnia Monte Carlo codes. Cross sections are calculated in the equivalent photon approximation using γ fluxes derived from electric dipole and charge form factors, and incorporating hadronic...

93. Modelling semi-exclusive particle production at the LHC

Photon-photon physics and hard diffraction

In this talk we will present the results of a new calculation of semi-exclusive photon-initiated production, that is either with intact outgoing protons or rapidity gaps present in the final state, and with no colour flow between the colliding LHC protons. This accounts for both the possibility of proton dissociation and the survival factor probability of no additional proton-proton...
