Description
Charm quarks are mostly produced in hard partonic scattering processes in the early stages of
a heavy-ion collision, before the quark-gluon plasma (QGP) is formed. Because of their large
mass the production cross section can be calculated using perturbative quantum
chromodynamics down to zero transverse momentum. Therefore, they are ideal probes of the
properties of this hot, dense, and strongly interacting medium.
Measurements of heavy-flavour tagged jets bring more relevant information of the initial
parton kinematics than traditional hadron measurements and can provide information on
heavy-quark energy loss in the QGP, in particular on how the radiated energy is dissipated in
the medium. Moreover, the study of charm-baryon production in heavy-ion collisions
provides unique information on hadronization mechanism.
This talk focuses on the latest results of charm-tagged jets and open charm production with
the ALICE detector at the LHC.
