Abstract

We investigate charmonium production in Pb+Pb collisions at LHC beam energy E_\text lab=2.76 A TeV at fixed-target experiment (√ s_NN=72 GeV). In the frame of a transport approach including cold and hot nuclear matter effects on charmonium evolution, we focus on the anti-shadowing effect on the nuclear modification factors R_AA and r_AA for the J/ψ yield and transverse momentum. The yield is more suppressed at less forward rapidity (y_lab≃2) than that at very forward rapidity (y_lab≃4) due to the shadowing and anti-shadowing in different rapidity bins.
