Description
In heavy-ion collisions, charm and beauty (heavy flavour) quarks are produced in the initial hard partonic interactions. They successively interact with the hot and dense Quark-Gluon Plasma (QGP) formed in such collisions. Therefore, measurements of heavy-flavour production provide relevant information on the properties of the QGP.
In Pb--Pb collisions, a strong suppression of heavy-flavour yields has been observed at high $p_{\rm T}$ with respect to pp collisions scaled by the number of binary collisions which is attributed to energy loss of heavy quarks in the QCD medium.
Further information about energy-loss mechanism can be obtained by measuring the production of jets containing charm and beauty.
In ALICE, inclusive jet production has been measured for $p_{\rm{T}}>$ 20 GeV/$c$ in pp and Pb-Pb collisions.
Heavy-flavour jets can be identified via heavy-flavour decay electrons inside the jet cone.
In this poster, we show studies of heavy-flavour jet production tagged by electrons from heavy-flavour hadron decays with ALICE.
