Transverse momentum dependence of D-meson production in Pb-Pb collisions at √sNN=2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Abstract: The production of prompt charmed mesons D0, D+ and D∗+, and their an- tiparticles, was measured with the ALICE detector in Pb-Pb collisions at the centre-of-mass energy per nucleon pair, √sNN, of 2.76TeV. The production yields for rapidity |y| < 0.5 are presented as a function of transverse momentum, pT, in the interval 1–36GeV/c for the centrality class 0–10% and in the interval 1–16 GeV/c for the centrality class 30–50%. The nuclear modification factor RAA was computed using a proton-proton reference at √√ s = 2.76 TeV, based on measurements at s = 7 TeV and on theoretical calculat ...Daha fazlası

Centrality dependence of ψ(2S) suppression in p-Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The inclusive production of the ψ(2S) charmonium state was studied as a function of centrality in p-Pb collisions at the nucleon-nucleon center of mass energy √sNN = 5.02 TeV at the CERN LHC. The measurement was performed with the ALICE detec- tor in the center of mass rapidity ranges −4.46 < ycms < −2.96 and 2.03 < ycms < 3.53, down to zero transverse momentum, by reconstructing the ψ(2S) decay to a muon pair. The ψ(2S) production cross section σψ(2S) is presented as a function of the collision cen- trality, which is estimated through the energy deposited in forward rapidity calorime- ters.

Measurement of D-meson production versus multiplicity in p–Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Abstract: The measurement of prompt D-meson production as a function of multiplic- ity in p–Pb collisions at √sNN = 5.02TeV with the ALICE detector at the LHC is re- ported. D0, D+ and D∗+ mesons are reconstructed via their hadronic decay channels in the centre-of-mass rapidity range −0.96 < ycms < 0.04 and transverse momentum interval 1 < pT < 24 GeV/c. The multiplicity dependence of D-meson production is examined by either comparing yields in p–Pb collisions in different event classes, selected based on the multiplicity of produced particles or zero-degree energy, with those in pp collisions ...Daha fazlası

Measurement of D+s production and nuclear modification factor in Pb-Pb collisions at √sNN =2.76TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Abstract: The production of prompt D+s mesons was measured for the first time in collisions of heavy nuclei with the ALICE detector at the LHC. The analysis was performed on a data sample of Pb-Pb collisions at a centre-of-mass energy per nucleon pair, √sNN, of 2.76 TeV in two different centrality classes, namely 0–10% and 20–50%. D+s mesons and their antiparticles were reconstructed at mid-rapidity from their hadronic decay channel D+s → φπ+, with φ → K−K+, in the transverse momentum intervals 4 < pT < 12 GeV/c and 6 < pT < 12GeV/c for the 0–10% and 20–50% centrality classes, respectively.
