abstract = {The first measurements of the production of muons and
electrons from heavy-flavour hadron decays in Xe–Xe
collisions at $\sqrt{s_{\rm NN}}$ = 5.44 TeV, using the
ALICE detector at the LHC, are reported. The measurement of
the nuclear modification factor $R_{AA}$ is performed as a
function of transverse momentum $p_T$ in several centrality
classes at forward rapidity (2.5 < y < 4) and midrapidity
(|y| < 0.8) for muons and electrons from heavy-flavour
hadron decays, respectively. A suppression by a factor up to
about 2.5 compared to the binary-scaled pp reference is
observed in central collisions at both central and forward
rapidities. The $R_{AA}$ of muons from heavy-flavour hadron
decays is compared to previous measurements in Pb–Pb
collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV. When the
nuclear modification factors are compared in the centrality
classes 0–10\% for Xe–Xe collisions and 10–20\% for
Pb–Pb collisions, which have similar charged-particle
multiplicity density, a similar suppression, with $R_{AA}$
∼ 0.4 in the $p_T$ interval 4 < $p_T$ < 8 GeV/c, is
observed. The comparison of the measured $R_{AA}$ values in
the two collision systems brings new insights on the
properties of the quark-gluon plasma by investigating the
system-size and geometry dependence of medium-induced parton
energy loss. The results of muons and electrons from
heavy-flavour hadron decays provide new constraints to model
calculations.},
