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
An overview of the recent results from ALICE, CMS and LHCb on the exclusive quarconium production will be presented.
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...
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...
