D$^{0}$-tagged jets in Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV with ALICE at the LHC
ORAL
Abstract
Heavy quarks, due to their large masses, are produced in the early stages of high-energy hadronic collisions in hard-scattering processes. Therefore, they are ideal probes of the quark-gluon plasma (QGP). The mass-dependent energy loss in the QGP is investigated using jets tagged by D$^{0}$ mesons. The modification of the yields as a function of jet transverse momentum in Pb--Pb collisions in comparison with pp collisions provides information on the charm-quark interaction with the medium. In this contribution the measurement of D$^{0}$-tagged jets in Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV with the ALICE detector will be presented. The presence of the charmed meson as a jet constituent enhances the rejection of jet combinatorial background allowing the study of the jet spectrum down to low $p_{\mathrm{T}}$, where probes are more sensitive to hot nuclear matter effects.
