Heavy quark photoproduction in k-perpendicular factorization approach

We investigate heavy quark photoproduction based on the

Nuclear shadowing and prompt photons in hadronic collisions at ultrarelativistic energies

In this paper we study the double

production in central diffractive processes considering the Resolved Pomeron model. Based on the nonrelativistic QCD (NRQCD) factorization formalism for the quarkonium production mechanism we estimate the rapidity and transverse momentum dependence of the cross section for the double

Multiple photon production in double parton scattering at the LHC

production in diffractive processes at LHC energies. The contributions of the color-singlet and color-octet channels are estimated and predictions for the total cross sections in the kinematical regions of the LHC experiments are also presented. Our results demonstrate that the contribution of central diffractive processes is not negligible and that its study can be useful to test the Resolved Pomeron model.
