Production of muons from heavy-flavour hadron decays in heavy-ion collisions with ALICE at the LHC

Measurements of the production of muons from heavy-flavour hadron decays at forward rapidity ($2.5<y<4.0$) in Pb–Pb collisions at $\sqrt{s_{\mathrm{N}\mathrm{N}}}=2.76$ and 5.02 TeV with the ALICE detector are presented along with the $R_{\mathrm{A}\mathrm{A}}$ measurements in different centrality intervals as a function of transverse momentum, $p_{\mathrm{T}}$. Results of the measured $R_{\mathrm{A}\mathrm{A}}$ at both energies are shown and are compared to the different model predictions.
