Investigating charm production and fragmentation via azimuthal correlations of prompt D mesons with charged particles in pp collisions at √s = 13 TeV
Original language description
Angular correlations of heavy-flavour and charged particles in high-energy proton-proton collisions are sensitive to the production mechanisms of heavy quarks and to their fragmentation as well as hadronisation processes. The measurement of the azimuthal-correlation function of prompt D mesons with charged particles in proton-proton collisions at a centre-of-mass energy of root s = 13 TeV with the ALICE detector is reported, considering D-0, D+, and D*(+) mesons in the transverse-momentum interval 3 < p(T) < 36 GeV/c at midrapidity (vertical bar y vertical bar < 0.5), and charged particles with p(T) > 0.3 GeV/c and pseudorapidity vertical bar eta vertical bar < 0.8. This measurement has an improved precision and provides an extended transverse-momentum coverage compared to previous ALICE measurements at lower energies. The study is also performed as a function of the charged-particle multiplicity, showing no modifications of the correlation function with multiplicity within uncertainties. The properties and the transverse-momentum evolution of the near- and awayside correlation peaks are studied and compared with predictions from various Monte Carlo event generators. Among those considered, PYTHIA8 and POWHEG+PYTHIA8 provide the best description of the measured observables. The obtained results can provide guidance on tuning the generators.
