Abstract
The azimuthal correlations of D mesons with charged particles were measured with the ALICE apparatus in pp collisions at root s = 7 TeV and p-Pb collisions at root sNN = 5.02 TeV at the Large Hadron Collider. D-0, 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 vertical bar y(cms)vertical bar < 0.5 (pp collisions) and -0.96 < y(cms) < 0.04 (p-Pb collisions) were correlated to charged particles with p(T) > 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.
