Inclusive transverse momentum distribution of negative (top) and positive (bottom) muons for the 0--90\% (left) and 0--10\% (right) centrality intervals in \PbPb collisions at \fivenn. The results of the fit to the inclusive spectrum using a combination of MC templates is shown as a continuous line, the green, pink and blue dashed lines representing the contributions of the \W-, \Z/$\gamma^*$- and heavy-flavour hadron decay muons, respectively. The bottom panels show the ratio of the data to the fit result.
