Sažetak
The first measurements of the production of muons and electrons from heavy-flavour hadron decays in Xe-Xe collisions at √sNN = 5.44 TeV, using the ALICE detector at the LHC, are reported. The measurement of the nuclear modification factor RAA is performed as a function of transverse momentum pT in several centrality classes at forward rapidity (2.5 < y <42.5<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 RAA of muons from heavy- flavour hadron decays is compared to previous measurements in Pb-Pb collisions at √sNN = 5.02 TeV. A similar suppression, with RAA ~ 0.4 in the pT interval 4 < pT < 8 GeV/cc, is observed in Pb-Pb and Xe- Xe collisions when the nuclear modification factors are compared in event classes with similar charged-particle multiplicity density. The comparison of the measured RAA values in the two collision systems brings new insights on the properties of the quark-gluon plasma by investigating the system-size and path-length dependence of medium-induced parton energy loss. The results of muons and electrons from heavy- flavour hadron decays provide new constraints to model calculations.
