The azimuthal correlations of D mesons with charged particles were measured with the ALICE apparatus in pp collisions at s = 7   T e V and p–Pb collisions at s N N = 5.02   T e V at the Large Hadron Collider. D 0 , D + , and D + mesons and their charge conjugates with transverse momentum 3 < p T < 16   G e V / c and rapidity in the nucleon-nucleon centre-of-mass system | y c m s | < 0.5 (pp collisions) and 0.96 < y c m s < 0.04 (p–Pb collisions) were correlated to charged particles with p T > 0.3   G e V / 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.
