W and Z boson production in p-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV

Abstract

The W and Z boson production was measured via the muonic decay channel in proton-lead collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV at the Large Hadron Collider with the ALICE detector. The measurement covers backward ($-4.46<y_{\mathrm{cms}}<-2.96$) and forward ($2.03<y_{\mathrm{cms}}<3.53$) rapidity regions, corresponding to Pb-going and p-going directions, respectively. The Z-boson production cross section, with dimuon invariant mass of $60<m_{\mu \mu }<120$ GeV/$c^2$ and muon transverse momentum ($p_{\mathrm{T}}^{\mu }$) larger than 20 GeV/$c$, is measured. The production cross section and charge asymmetry of muons from W-boson decays with $p_{\mathrm{T}}^{\mu }>10$ GeV/$c$ are determined. The results are compared to theoretical calculations both with and without including the nuclear modification of the parton distribution functions. The W-boson production is also studied as a function of the collision centrality: the cross section of muons from W-boson decays is found to scale with the average number of binary nucleon-nucleon collisions within uncertainties.
