\avTaa-scaled yield of muons from \Wminus and \Wplus decays in \PbPb collisions at \fivenn for muons with $\pt^\mu > 10$ \GeVc and $2.5 < y^\mu_{\rm cms} < 4.0$. The measured production is compared with HG-PYTHIA calculations of the \RPbPb of hard scatterings scaled with the centrality-averaged production in 0--90\% centrality, indicated as dashed lines. The horizontal bars correspond to the width of the centrality intervals, the vertical bars and boxes indicate the statistical and systematic uncertainties, respectively.
