Description

Charm and beauty quarks (heavy flavours) are produced in hard scattering processes in the early stages of heavy-ion collisions, and propagate through the hot and dense QCD matter (QGP) produced as a consequence of the collision. Therefore, they are sensitive probes to characterize the QGP properties.
The measurement of the elliptic flow (${v_{2}}$) of open heavy-flavour particles at low ${p_{T}}$ can give insight into the participation of the heavy quarks in the collective expansion of the system and their thermalization in the medium. While at high ${p_{T}}$, it allows us to investigate the path-length dependence of parton energy loss.
In this poster, we will present the measurement of ${v_{2}}$ for electrons from open heavy-flavour hadron decays in Pb-Pb collisions at $\sqrt{s_{NN}} = $5.02 TeV with ALICE. The electrons are identified by means of Time Projection Chamber (TPC) and the ElectroMagnetic Calorimeters (EMCal).
