Cold and Hot Nuclear Matter Effects on Charmonium Production in p+Pb Collisions at LHC Energy

We study cold and hot nuclear matter effects on charmonium production in p+Pb collisions at $\sqrt{s_\text{NN}}=5.02$ TeV in a transport approach. At the forward rapidity, the cold medium effect on all the $c\bar c$ states and the hot medium effect on the excited $c\bar c$ states only can explain well the $J/ψ$ and $ψ'$ yield and transverse momentum distribution measured by the ALICE collaboration, and we predict a significantly larger $ψ'$ $p_\text{T}$ broadening in comparison with $J/ψ$. However, we can not reproduce the $J/ψ$ and $ψ'$ data at the backward rapidity with reasonable cold and hot medium effects.
