Heavy-flavour tagged jet production compared to simulations

Azimuthal correlations of D mesons with charged particles

Abstract

This contribution summarises the results on heavy-flavour correlations and jets measured with ALICE detector. Studies of D$^{0}$-tagged jets are presented in various collision systems and energies. The measurement of the fraction of jet momentum carried by the D$^{0}$ meson in the direction of the jet axis ($z_{\rm ||}^{\rm ch,jet}$) in pp collisions at $\sqrt{s}$ = 5.02 and 13 TeV as well as the nuclear modification factor in p--Pb and Pb--Pb collisions are presented. The measurements of the production of jets tagged by electrons from heavy-flavour decays in pp and p--Pb are compared to expectations from POWHEG+PYTHIA8 simulations. The $p_{\rm T}$-differential cross section of b-tagged jets in p--Pb collisions is also reported and compared to expectations from POWHEG event generator. The azimuthal correlation of D mesons with charged particles in pp and p--Pb collisions are also presented.
