PoS(EPS-HEP2015)511 The role of intrinsic charm in the proton via photon production in association with a charm quark S. Rostami Physics Department, Semnan University, Semnan, Iran E-mail: asalrostami.phy@gmail.com A. Khorramian ∗ Physics Department, Semnan University, Semnan, Iran School of Particles and Accelerators, Institute for Research in Fundamental Sciences (IPM), P.O.Box 19395-5531, Tehran, Iran E-mail: khorramiana@theory.ipm.ac.ir A. Aleedaneshvar Physics Department, Semnan University, Semnan, Iran E-mail: alireza.daneshvar@gmail.com In this paper, we carry out a comparative analysis of the impact of intrinsic charm on differen- tial cross section of photon c-jet production in pp collision at the LHC and p ¯ p collision at the Tevatron. For this aim, we use the non-singlet evolution of the intrinsic heavy quark distribution technique which allows us to evolve intrinsic heavy quark distribution independently from the gluon and other parton distribution functions.
