Measurement of azimuthal correlations of D mesons with charged particles in pp collisions at √{s}=7 TeV and p-Pb collisions at {√{{{s}}_riptscriptstyle {NN}}}=5.02 TeV
Abstract
The azimuthal correlations of D mesons with charged particles were measured with the ALICE apparatus in pp collisions at {√{s}}=7 \mathrm {TeV} and p-Pb collisions at {√{{{s}}_riptscriptstyle {NN}}}=5.02 \mathrm {TeV} at the Large Hadron Collider. D0, {D+}, and {D^{*+}} mesons and their charge conjugates with transverse momentum 3<{p}T<16 \mathrm {GeV}/c and rapidity in the nucleon-nucleon centre-of-mass system |y_cms|<0.5 (pp collisions) and -0.96<y_cms<0.04 (p-Pb collisions) were correlated to charged particles with {p}T>0.3 \mathrm {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.
