Abstract：
In the Paper we give some results about nuclear shadowing of real photon at LHC. We show that shadowing grows strong with the increasing of Photon energy E_γ. The CMS energy dependence of total cross sections of production of ρ,ω and φ in the process γ+A→V+A is also given. The results show that there is a critical energy point, above which the nuclear shadowing is strong enough to be observed.
