Dilepton production through timelike Compton scattering within the kT-factorization approach

In this work we consider the dilepton production via timelike Compton scattering (TCS) in electron-proton and proton-proton collisions. In particular, the differential cross section in terms of the dilepton invariant mass and rapidity is computed within the k(T)-factorization approach. Besides, we utilize distinct unintegrated gluon distributions (UGD) in order to compare their impact on the differential cross section of TCS in pp (ep) collisions evaluated at the LHC (LHeC), HL-LHC (LHeC), HE-LHC (LHeC), and FCC-hh (eh) center-of-mass energies.
