The azimuthal correlations of D mesons with
charged particles were measured with the ALICE apparatus
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 nucleonnucleon
centre-of-mass system |ycms| < 0.5 (pp collisions)
and −0.96 < ycms < 0.04 (p–Pb collisions) were correlated
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 compatible
within uncertainties in the two collision systems. The
data are described within uncertainties by Monte-Carlo simulations
based on PYTHIA, POWHEG, and EPOS 3 event
generators.
