Dynamical simulation on production of ${\mathrm{W}}^{\pm }$ and ${\mathrm{Z}}^0$ bosons in p-p, p-Pb (Pb-p), and Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV with PACIAE

Abstract

In this paper, production of ${\mathrm{W}}^{\pm }$ and ${\mathrm{Z}}^0$ vector bosons in p-p, p-Pb (Pb-p), and Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV is dynamically simulated with a parton and hadron cascade model PACIAE. ALICE data of ${\mathrm{Z}}^0$ production is found to be reproduced fairly well. A prediction for ${\mathrm{W}}^{\pm }$ 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 ${\mu }^{\pm }$ charge asymmetry in pp, pn, np, and nn collisions and in minimum bias p-Pb, Pb-p and Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV, respectively.
