Measurement of angular correlations between $\mathrm{D}$ mesons and charged particles in pp and p-Pb collisions with ALICE at the LHC

Abstract

We have studied the azimuthal correlations between ${\mathrm{D}}^0$, ${\mathrm{D}}^{+}$ and ${\mathrm{D}}^{\ast +}$ mesons and charged particles in pp collisions at $\sqrt{s}=7\mathrm{TeV}$ and p-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02\mathrm{TeV}$ at the Large Hadron Collider. D mesons were reconstructed from their hadronic decays in the central rapidity region and in the transverse-momentum range 3 $\le p_T\le$ 16 $\mathrm{GeV}/c$, and they were correlated to charged particles reconstructed in the pseudo-rapidity range $|\eta |<0.8$. A comparative study of the pp results with Monte Carlo Pythia studies and also with p-Pb results are presented here.
