Abstract

We investigate charmonium production in Pb+Pb collisions at LHC beam energy $E_{\text {lab}}$ =2.76 A TeV at fixed-target experiment ( $\sqrt {s_{\text{NN}}}$ =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 $J/\psi$ yield and transverse momentum. The yield is more suppressed at less forward rapidity ( $y_\text{lab}\simeq$ 2) than that at very forward rapidity ( $y_\text{lab}\simeq$ 4) due to the shadowing and anti-shadowing in different rapidity bins.
