Description
We study cold and hot nuclear matter effects on charmonium production in p+Pb collisions at$\sqrt{s_{NN}}$ = 5.02 TeV in a transport approach. As cold nuclear matter effects give almost the same modification on different $c\bar c$ states at the LHC energy, different nuclear modification factors of $J/\psi$ and $\psi^\prime$ indicate the existence of the hot medium. In forward rapidity, we can explain well the $J/\psi$ and $\psi^\prime$ yield and transverse momentum distribution measured by the ALICE collaboration, and we predict a significantly larger $\psi^\prime$ broadening in comparison with $J/\psi$. However, we can not reproduce the $J/\psi$ and $\psi^\prime$ data at the backward rapidity with reasonable cold and hot medium effects.
