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

TL;DR

This paper reports on measurements of muons from heavy-flavour hadron decays in lead-lead collisions at the LHC, analyzing their suppression patterns across energies and centralities to understand quark-gluon plasma effects.

Contribution

It provides new experimental data on muon production from heavy-flavour decays at forward rapidity in Pb--Pb collisions at two LHC energies, with comparisons to theoretical models.

Findings

Measured R_AA shows suppression of muons at both energies.

Results vary with collision centrality and transverse momentum.

Data compared to multiple theoretical predictions.

Abstract

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