摘要：

We study cold and hot nuclear matter effects on charmonium production in p+Pb collisions at root S-NN = 5.02 TeV in a transport approach. At the forward rapidity, the cold medium effect on all the a states and the hot medium effect on the excited a states only can explain well the J/psi and psi' yield and transverse momentum distribution measured by the ALICE collaboration, and we predict a significantly larger p(T) broadening in comparison with J/psi. However, we can not reproduce the J/psi and psi' data at the backward rapidity with reasonable cold and hot medium effects. (C) 2016 The Authors. Published by Elsevier B.V.
