摘要：
We have studied the effects of nonlinear scale evolution of the parton distribution functions to charm production in pp collisions at centre-of-mass energies of 5.5, 8.8 and 14 TeV. We find that the differential charm cross section can be enhanced up to a factor of 4-5 at low p(T). The enhancement is quite sensitive to the charm quark mass and the renormalization/factorization scales.
