Charm jet production and properties in pp, p-Pb, and PbPb collisions measured with ALICE at the LHC

International audienceIn Pb-Pb collisions at the LHC, a hot and dense medium of deconfined quarks and gluons isformed (Quark-Gluon Plasma, QGP).The QGP is conjectured to be the state of matter of the early Universe up to few microsecondsafter the Big Bang and may still exist in the core of neutron stars. One of the most strikingsignatures of the QGP formation in heavy-ion collisions is the suppression of jet production.This phenomenon, called jet quenching, is ascribed to the energy lost by the initial parton whiletraveling through the QGP medium.Heavy quarks lose energy via subsequent elastic scatterings with the medium constituents, and/orthrough gluon radiation. Theoretical models predict that energy loss depends on the color chargeand mass of the hard-scattered parton traversing the medium. Such mass dependence can bestudied by measuring the production of hadrons and jets containing heavy-quarks in pp, p-Pband Pb-Pb collisions at the LHC.In this contribution we will present the measurements of c-jet production in pp, p-Pb and Pb-Pbcollisions performed with the ALICE detector at the LHC. The results obtained with pp and p-Pbdata will be compared with predictions from event generators. Charm jets are tagged by requiringthe presence of a D meson among its constituents. Thanks to the exclusive reconstruction ofD-meson hadronic decay channels, the measurement of the jet-momentum fraction carried by theD meson is possible. This provides useful information to investigate charm fragmentation andproduction processes. The prospects for measuring b-jet production with ALICE will be alsodiscusse
