Improved modeling of $\gamma \gamma$ processes in ultraperipheral collisions at hadron colliders

Nicolas Crépet, David d'Enterria, Hua-Sheng Shao

The CERN LHC is not only the current energy-frontier collider for parton-parton collisions, but has proven a powerful photon collider providing photon-photon ($\gamma \gamma$) collisions at c…
