J/ψ elliptic and triangular flow in Pb–Pb collisions at √ sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The production of K∗(892)0 and φ(1020) mesons has been measured in p–Pb collisions at √sNN = 5.02 TeV. K∗0 and φ are reconstructed via their decay into charged hadrons with the ALICE detector in the rapidity range −0.5 < y < 0. The transverse momentum spectra, measured as a function of the multiplicity, have a pT range from 0 to 15 GeV/c for K∗0 and from 0.3 to 21 GeV/c for φ. Integrated yields, mean transverse momenta and particle ratios are reported and compared with results in pp collisions at √s = 7 TeV and Pb–Pb collisions at √sNN = 2.76 TeV. In Pb–Pb and p–Pb collisions, K∗0 and φ probe ...Daha fazlası

Non-strange and strange D-meson and charm-baryon production in heavy-ion collisions measured with ALICE at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

We present recent results on strange and non-strange D-meson production measured with ALICE in Pb-Pb collisions at the LI-IC. In addition, the measurements of the Lambda(+)(c)-baryon production and of the Lambda(+)(c)/D-0 ratio in pp, p-Pb, and, for the first time ever, Pb-Pb collisions are reported.

Υ suppression at forward rapidity in Pb–Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Inclusive Υ(1S) and Υ(2S) production have been measured in Pb–Pb collisions at the centre-of-mass energy per nucleon–nucleon pair √sNN = 5.02 TeV, using the ALICE detector at the CERN LHC. The Υ mesons are reconstructed in the centre-of-mass rapidity interval 2.5 < y < 4 and in the transverse- momentum range pT < 15 GeV/c, via their decays to muon pairs. In this Letter, we present results on the inclusive Υ(1S) nuclear modification factor RAA as a function of collision centrality, transverse momentum and rapidity. The Υ(1S) and Υ(2S) RAA, integrated over the centrality range 0–90%, are 0.37± 0 ...Daha fazlası

Searches for transverse momentum dependent flow vector fluctuations in Pb–Pb and p–Pb collisions at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

The measurement of azimuthal correlations of charged particles is presented forPb–Pbcollisionsat√sNN =2.76TeVandp–Pbcollisionsat√sNN =5.02TeVwiththe ALICE detector at the CERN Large Hadron Collider. These correlations are measured for the second, third and fourth order flow vector in the pseudorapidity region |η| < 0.8 as a function of centrality and transverse momentum pT using two observables, to search for evidence of pT-dependent flow vector fluctuations. For Pb–Pb collisions at 2.76TeV, the measurements indicate that pT-dependent fluctuations are only present for the second order flow vec ...Daha fazlası

φ meson production at forward rapidity in Pb–Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

φ meson measurements provide insight into strangeness production, which is one of the key observables for the hot medium formed in high-energy heavy-ion colli- sions. ALICE measured φ production through its decay in muon pairs in Pb–Pb collisions at √sNN = 2.76 TeV in the intermediate transverse momentum range 2 < pT < 5 GeV/c and in the rapidity interval 2.5 < y < 4. The φ yield was measured as a function of the transverse momen- tum and collision centrality. The nuclear modification factor was obtained as a function of the average number of par- ticipating nucleons. Results were compared wit ...Daha fazlası

Suppression of Λ(1520) resonance production in central Pb-Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The production yield of the Λ(1520) baryon resonance is measured at midrapidity in Pb-Pb collisions at sNN = 2.76 TeV with the ALICE detector at the Large Hadron Collider (LHC). The measurement is performed in the Λ(1520)→pK- (and charge conjugate) hadronic decay channel as a function of the transverse momentum (pT) and collision centrality. The ratio of the pT-integrated production of Λ(1520) baryons relative to Λ baryons in central collisions is suppressed by about a factor of 2 with respect to peripheral collisions. This is the first observation of the suppression of a baryonic resonance at ...Daha fazlası

Inclusive J/ψ production at forward and backward rapidity in p–Pb collisions at √sNN = 8.16 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Inclusive J/ψ production is studied in p-Pb interactions at a centre-of-mass energy per nucleon-nucleon collision sNN−−−√=8.16 TeV, using the ALICE detector at the CERN LHC. The J/ψ meson is reconstructed, via its decay to a muon pair, in the centre-of-mass rapidity intervals 2.03< ycms< 3.53 and −4.46< ycms< −2.96, where positive and negative ycms refer to the p-going and Pb-going direction, respectively. The transverse momentum coverage is pT< 20 GeV/c. In this paper, ycms- and pT-differential cross sections for inclusive J/ψ production are presented, and the corresponding nuclear modificati ...Daha fazlası

Inclusive J/ψ production at mid-rapidity in pp collisions at √s = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Inclusive J/ψ production is studied in minimum-bias proton-proton collisions at a centre-of-mass energy of √s = 5.02 TeV by ALICE at the CERN LHC. The measurement is performed at mid-rapidity (|y| < 0.9) in the dielectron decay channel down to zero transverse momentum pT, using a data sample corresponding to an integrated luminosity tion is dσ/dy = 5.64 ± 0.22(stat.) ± 0.33(syst.) ± 0.12(lumi.) μb. The pT-differential cross section d2σ/dpTdy is measured in the pT range 0–10GeV/c and compared with state-of- the-art QCD calculations. The J/ψ ⟨pT⟩ and ⟨p2T⟩ are extracted and compared with results ...Daha fazlası

W and Z boson production in p-Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The W and Z boson production was measured via the muonic decay chan- nel in proton-lead collisions at √sNN = 5.02 TeV at the Large Hadron Collider with the ALICE detector. The measurement covers backward (−4.46 < ycms < −2.96) and for- ward (2.03 < ycms < 3.53) rapidity regions, corresponding to Pb-going and p-going direc- tions, respectively. The Z-boson production cross section, with dimuon invariant mass of 60 < mμμ < 120GeV/c2 and muon transverse momentum (pμT) larger than 20GeV/c, is measured. The production cross section and charge asymmetry of muons from W-boson decays with pμT > 10 GeV ...Daha fazlası
