Description
The positive elliptic flow ($v_{2}$) of open heavy-flavour particles observed in semi-central Pb--Pb collisions at LHC energies indicates that heavy quarks suffered strong interactions in the deconfined QCD medium and participated in the collective motion of the medium. Recent observations in high-multiplicity pp and p--Pb collisions show remarkable similarities with Pb-Pb collisions and suggest the presence of collectivity, whose origin is still debated.
In this contribution, the elliptic flow of open heavy-flavour hadron decay muons at forward rapidity ($2.5 < y < 4$) in p--Pb collisions at $8.16$ TeV with the ALICE detector will be presented. The results are obtained using Q-cumulants and two-particle correlation methods. The measurements will set constraints on the initial-state fluctuations on heavy-quark production. Moreover, the results will be compared with measurements obtained in p-Pb collisions at $5.02$ TeV and with those performed at mid-rapidity for electrons from heavy-flavour hadron decays. Comparisons with model predictions will be presented as well.
