Description

We discuss recent developments in the Sherpa event generator with regard to UPCs. Different form factors for the photon flux for both protons and heavy nuclei are compared and finite size effects of the emitters are taken into account. We present preliminary results for jet prodcution at NLO matched to the parton shower using MC@NLO, as well as NLO QED calculations for exclusive muon-pair production at the LHC, comparing to measurements by ATLAS and CMS.
