Measurements of heavy-flavour correlations and jets with ALICE at the LHC

Abstract

In this work, the latest heavy-flavour correlation and jet measurements at mid-rapidity with the ALICE detector in pp, p–Pb and Pb–Pb collisions from the LHC Run 2 are reported. In particular, the results of azimuthal correlation measurements of D mesons with charged particles in pp collisions at √s = 13 TeV and in p–Pb collisions at √sNN = 5.02 TeV are presented. Studies on the centrality-dependent azimuthal correlations of heavy-flavour hadron decay electrons with charged particles in Pb–Pb collisions at √sNN = 5.02 TeV are shown. In addition, measurements of D-meson tagged jet production in pp collisions at √s = 7 TeV and in p–Pb collisions at √sNN = 5.02 TeV are presented, including studies in pp collisions of the jet momentum fraction carried by the D meson. A first result on the D-meson tagged jet nuclear modification factor in central Pb–Pb collisions at √sNN = 5.02 TeV is also reported.
