Abstract：
Direct hard PhotoProduction of J/ψ and γ at LHC Pb-Pb collisions with CMS energy 5.5ATeV, and Ca-Ca collisions with CMS energy 7ATeV, are discussed in the process: A+A→A+J/ψ(γ) + X. It turns out that the processes can be used to testing the gluon distribution in the nucleus, as well as to studying the mechanism of large P_t gluon and heavy quark fragmentation of J/ψ.
