Abstract

The azimuthal correlations of D mesons with charged particles were measured with the ALICE appara- tus in pp collisions at √s = 7 TeV and p–Pb collisions at √sNN = 5.02 TeV at the Large Hadron Collider. D0 , D+ , and D∗+ mesons and their charge conjugates with transverse momentum 3 < pT < 16 GeV/c and rapidity in the nucleon- nucleon centre-of-mass system | ycms | < 0.5 (pp collisions) and −0.96 < ycms < 0.04 (p–Pb collisions) were corre- lated to charged particles with pT > 0.3 GeV/c. The yield of charged particles in the correlation peak induced by the jet containing the D meson and the peak width are compat- ible within uncertainties in the two collision systems. The data are described within uncertainties by Monte-Carlo sim- ulations based on PYTHIA, POWHEG, and EPOS 3 event generators.
