WG2: Event Simulations and Monte Carlo Tools

In this study, I am going to present the development of photoproduction at NLO in the fixed-order mode of MadGraph5_aMC@NLO where the photon is either coming from an electron or from a proton in an ultra-peripheral collision at the LHC. In addition, I will also present the development for asymmetric hadron collisions in order to provide predictions e.g. for proton-nucleus collisions

WG4: Heavy-quark and Quarkonium Physics

We present the first study of coherent exclusive J/psi photoproduction in ultraperipheral collisions (UPCs) of heavy and intermediate ions at the LHC in the framework of collinear factorization and next-to-leading order (NLO) perturbative QCD and make predictions for the J/psi rapidity distributions for the cases of lead (Pb) and oxygen (O) beams. We confirm the general expectation of a...

WG7: Parton tomography from 1D to 5D

While hadronic structure is experimentally probed by processes such as DIS and
DVCS, both lattice and continuum techniques are employed to corroborate such re-
sults from a theoretical perspective. On the continuum side, the Fadeev equations
provide a fully covariant approach to three body interactions convenient for describing
three quark hadronic states. However, the...
