Measurement of azimuthal correlations of D mesons and charged particles in pp collisions at $\sqrt{s}=7$ TeV and p-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV

Abstract

The azimuthal correlations of D mesons and charged particles were measured with the ALICE detector in pp collisions at $\sqrt{s}=7$ TeV and p-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV at the Large Hadron Collider. D${}^0$, D${}^{+}$, and D${}^{\ast +}$ mesons and their charge conjugates with transverse momentum $3<p_{\mathrm{T}}<16$ GeV/$c$ and rapidity in the nucleon-nucleon centre-of-mass system $|y_{\mathrm{cms}}|<0.5$ (pp collisions) and $-0.96<y_{\mathrm{cms}}<0.04$ (p-Pb collisions) were correlated to charged particles with $p_{\mathrm{T}}>0.3$ Gev/$c$. The properties of the correlation peak induced by the jet containing the D meson, described in terms of the yield of charged particles in the peak and peak width, are compatible within uncertainties between the two collision systems, and described by Monte-Carlo simulations based on the PYTHIA, POWHEG and EPOS 3 event generators.
