# Measurement of azimuthal correlations of D mesons with charged particles in pp collisions at $\sqrt{s}=7$ TeV and p–Pb collisions at ${\sqrt{{{s}}_{\scriptscriptstyle {\mathrm{NN}}}}}=5.02$ TeV

The European Physical Journal C, Apr 2017

The azimuthal correlations of D mesons with charged particles were measured with the ALICE apparatus in pp collisions at ${\sqrt{s}}=7~\mathrm {TeV}$ and p–Pb collisions at ${\sqrt{{{s}}_{\scriptscriptstyle {\mathrm{NN}}}}}=5.02~\mathrm {TeV}$ at the Large Hadron Collider. $\mathrm{D}^{0}$, ${\mathrm{D}^{+}}$, and ${\mathrm{D}^{*+}}$ mesons and their charge conjugates with transverse momentum $3<{p}_{\mathrm{T}}<16~\mathrm {GeV}/c$ 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 ${p}_{\mathrm{T}}>0.3~\mathrm {GeV}/c$. 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.
