Azimuthal correlations of prompt D mesons with charged particles in pp and p-Pb collisions at root s(NN)=5.02 TeV
Popis výsledku v původním jazyce
The measurement of the azimuthal-correlation function of prompt D mesons with charged particles in pp collisions at root s = 5.02 TeV and p-Pb collisions at root s(NN) = 5.02 TeV with the ALICE detector at the LHC is reported. The D-0, D+, and D*+ mesons, together with their charge conjugates, were reconstructed at midrapidity in the transverse momentum interval 3 < p(T) < 24 GeV/c and correlated with charged particles having p(T) > 0.3 GeV/c and pseudorapidity vertical bar eta vertical bar < 0.8. The properties of the correlation peaks appearing in the near- and away-side regions (for Delta phi approximate to 0 and Delta phi approximate to pi, respectively) were extracted via a fit to the azimuthal correlation functions. The shape of the correlation functions and the near- and away-side peak features are found to be consistent in pp and p-Pb collisions, showing no modifications due to nuclear effectswithin uncertainties. The results are compared with predictions from Monte Carlo simulations performed with the PYTHIA, POWHEG+PYTHIA, HERWIG, and EPOS 3 event generators.
