Four-jet and three-jet plus gamma DPS production in pp and pA collisions at the LHC — •Oleh Fedkevych and Anna Kulesza — Institut für Theoretische Physik, Wilhelm-Klemm-Straße 9, 48149 Münster, Deutschland

In spite of the recent progress in both theoretical and experimental studies many aspects of proton-proton (pp) and proton-nucleus (pA) collisions still require a detail investigation. At high collision energies, the probability of simultaneous scatterings of different pairs of partons, contributing to the same inelastic event, has to be considered. In particular, double parton scattering (DPS) processes can also play a dominant role for some specific kinematic regions of multi-jet production.

In this talk we will discuss the DPS contribution to four-jet and three-jet plus gamma production in pp and pA collisions as well as its dependence on different kinematical cuts and different phenomenological assumptions.
