Abstract

In this paper we study the Z, jet, , and jet production in pp collisions at the LHC considering different models for the intrinsic charm content of the proton. We analyze the impact of the intrinsic charm in the rapidity and transverse momentum distributions for these different processes. Our results indicated that differently from the other processes, the cross section is strongly affected by the presence of the intrinsic charm. Moreover, we propose the analysis of the ratios and and we demonstrate that these observables can be used as a probe of the intrinsic charm.
