Azimuthal correlations of prompt D mesons with charged particles in pp and p–Pb collisions at √sNN=5.02 TeV
(2020) [Journal article]The measurement of the azimuthal-correlation function of prompt D mesons with charged particles in pp collisions at √s = 5.02 TeV and p–Pb collisions at √sNN = 5.02 TeV with the ALICE detector at the LHC is reported. The ... -
D-meson azimuthal anisotropy in midcentral Pb-Pb collisions at √sNN=5.02 TeV
(2018) [Journal article]The azimuthal anisotropy coefficient v2 of prompt D0 , Dþ , D*þ , and Dþs mesons was measured in midcentral (30%–50% centrality class) Pb-Pb collisions at a center-of-mass energy per nucleon pair √sNN¼ 5.02 TeV, with the ... -
D-meson production in high energy pA collisions within the QCD color dipole transverse momentum representation
(2022) [Journal article]The D-meson production is investigated by considering the unintegrated gluon distribution within the dipole approach in the momentum representation. We analyze the D-meson spectrum accounting for the effects of nonlinear ... -
Event-Shape Engineering for the D-meson elliptic flow in mid-central Pb-Pb collisions at √sNN = 5.02 TeV
(2019) [Journal article]The production yield of prompt D mesons and their elliptic ow coe cient v2 were measured with the Event-Shape Engineering (ESE) technique applied to mid-central (10{30% and 30{50% centrality classes) Pb-Pb collisions at ... -
Investigating charm production and fragmentation via azimuthal correlations of prompt D mesons with charged particles in pp collisions at √s = 13 TeV
(2022) [Journal article]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. ... -
Matter-antimatter asymmetry and non-inertial effects
(2021) [Journal article]We investigate non-inertial effects on CP-violating processes using a model, based on the framework of quantum field theory in curved spacetimes, devised to account for the decay of accelerated particles. We show that the ... -
Measurement of beauty and charm production in pp collisions at √s = 5.02 TeV via non-prompt and prompt D mesons
(2021) [Journal article]The pT-differential production cross sections of prompt and non-prompt (pro duced in beauty-hadron decays) D mesons were measured by the ALICE experiment at midrapidity (|y| < 0.5) in proton-proton collisions at √ s = 5.02 ... -
Measurement of D0, D+, D*+ and D+s production in pp collisions at √s=5.02 TeV with ALICE
(2019) [Journal article]The measurements of the production of prompt D0, D+, D*+, and D+ s mesons in proton–proton (pp) collisions at √ s = 5.02 TeV with the ALICE detector at the Large Hadron Collider (LHC) are reported. D mesons were reconstructed ... -
Measurement of prompt D0 and D_0 meson azimuthal anisotropy and search for strong electric fields in PbPb collisions at √sNN = 5.02 TeV
(2021) [Journal article]The strong Coulomb field created in ultrarelativistic heavy ion collisions is expected to produce a rapidity dependent difference (v2) in the second Fourier coefficient of the azimuthal distribution (elliptic flow, v2) ... -
Measurement of the production of charm jets tagged with D0 mesons in pp collisions at √s = 5.02 and 13 TeV
(2023) [Journal article]The measurement of the production of charm jets, identified by the presence of a D0 meson in the jet constituents, is presented in proton–proton collisions at centre-of mass energies of √s = 5.02 and 13 TeV with the ALICE ... -

The color evaporation model in diffractive J/[Psi] photoproduction
(1999) [Journal article]Our goal is the study of color effects on the J/[Psi] mesons production, as well as the study of their elastic production. We use the color evaporation model CEM, where a single factor takes into account the probability ... -
