Hard photoproduction of J/ψ and Υ at large hadron collider Pb-Pb collisions with center of mass energy 6300 AGeV is discussed in the process Pb + Pb → Pb + J/ψ(Γ) + X with three types of equivalent photon spectrum function. It turns out that in hard photoproduction the J/ψ cross section is dominated by the gluon and heavy quark fragmentation, especially the gluon fragmentation is very important at large pt, while the Υ cross section is dominated by the leading order process. It may be conclude from the result that the hard photoproductio...
