Abstract

In this paper, production of \rm W^± and \rm Z⁰ vector bosons in p-p, p-Pb (Pb-p), and Pb-Pb collisions at √s_{\rm NN}=5.02 TeV is dynamically simulated with a parton and hadron cascade model PACIAE. ALICE data of \rm Z⁰ production is found to be reproduced fairly well. A prediction for \rm W^± production is given in the same collision systems, at the same energy and at the same energy. An interesting isospin-effect is observed in the sign-change of μ^± charge asymmetry in pp, pn, np, and nn collisions and in minimum bias p-Pb, Pb-p and Pb-Pb collisions at √s_{\rm NN}=5.02 TeV, respectively.
