D+s production at central rapidity in Pb Pb collisions at sqrt{s_NN} = 2.76 TeV with the ALICE detector  [PDF]
Gian Michele Innocenti,for the ALICE Collaboration
Physics , 2012, DOI: 10.1016/j.nuclphysa.2013.02.042
Abstract: We present the measurement of the D+s production in pp collisions at sqrt{s} = 7 TeV and in Pb Pb collisions at sqrt{s_NN} =2.76 TeV performed with the ALICE detector at central rapidity through the reconstruction of the hadronic decay channel D+s-> K+K-pi+. The preliminary results of the D+s nuclear modification factor will be presented.
J/Psi production at forward rapidity in Pb-Pb collisions at sqrt(s_NN) = 2.76 TeV, measured with the ALICE detector  [PDF]
P. Pillot,for the ALICE Collaboration
Statistics , 2011, DOI: 10.1088/0954-3899/38/12/124111
Abstract: In the ALICE experiment, at forward rapidity (2.5 < y < 4), the production of heavy quarkonium states is measured via their mu+ mu- decay channels. We present the first measurement of inclusive J/Psi production, down to pT = 0, from Pb-Pb data collected at the LHC at sqrt(s_NN) = 2.76 TeV. Preliminary results on the nuclear modification factor (R_AA) and the central to peripheral nuclear modification factor (R_CP) show J/Psi suppression with no significant centrality dependence and an integrated R_AA(0-80%) = 0.49 \pm 0.03(stat.) \pm 0.11(syst.).
Charged particle directed flow in Pb-Pb collisions at sqrt{s_NN} = 2.76 TeV measured with ALICE at the LHC  [PDF]
Ilya Selyuzhenkov,for the ALICE Collaboration
Physics , 2011, DOI: 10.1088/0954-3899/38/12/124167
Abstract: Charged particle directed flow at midrapidity, |eta|<0.8, and forward rapidity, 1.7 < |eta|<5.1, is measured in Pb-Pb collisions at sqrt{s_NN} = 2.76 TeV with ALICE at the LHC. Directed flow is reported as a function of collision centrality, charged particle transverse momentum, and pseudo-rapidity. Results are compared to measurements at RHIC and recent model calculations for LHC energies.
Open heavy-flavour production in pp and Pb-Pb collisions at the LHC, measured with ALICE at central rapidity  [PDF]
A. Rossi for the ALICE Collaboration
Physics , 2013,
Abstract: The ALICE experiment studies nucleus-nucleus collisions at the LHC in order to investigate the properties of QCD matter at extreme energy densities. The measurement of open charm and open beauty production allows to investigate the interaction of heavy quarks with the hot and dense medium formed in high-energy nucleus-nucleus collisions. In particular, in-medium energy loss is predicted to be different for gluons, light quarks and heavy quarks and to depend on the medium energy density and size. ALICE has measured open heavy-flavour particle production at central rapidity in several decay channels in Pb-Pb and pp collisions at sqrt{s_NN} = 2.76 TeV and sqrt{s} = 2.76, 7 TeV respectively. The results obtained from the reconstruction of D meson decays at central rapidity and from electrons from heavy-flavour hadron decay will be presented.
D meson nuclear modification factors in Pb-Pb collisions at sqrt(s_NN) = 2.76 TeV with the ALICE detector  [PDF]
Alessandro Grelli for the ALICE collaboration
Physics , 2012, DOI: 10.1016/j.nuclphysa.2013.02.096
Abstract: The measurement of D meson production provides key tests for parton energy-loss models, which predict that charm quarks should experience less in-medium energy loss than light quarks and gluons. The ALICE experiment has measured the production of prompt D^(0), D^(+) and D^(*+) mesons in pp and Pb-Pb collisions at the LHC at sqrt(s) = 7 and 2.76 TeV and at sqrt(s_NN) = 2.76 TeV, respectively, via the exclusive reconstruction of their hadronic decay. The pT-differential production yields in the range 2 < pT < 16 GeV/c at central rapidity, |y| < 0.5, were used to calculate the nuclear modification factor. A suppression of a factor 3 to 4 for transverse momenta larger than 5 GeV/c in the 20% most central collisions was observed. Preliminary results in an extended pT-range, using the data sample collected during the 2011 Pb-Pb run, together with the first measurement of D^(+)_(s) nuclear modification factor will be shown.

Abstract: Selected ALICE results on the global event properties, particle spectra, azimuthal anisotropy, heavy flavour and quarkonium production in Pb-Pb collisions at sqrt(s_NN) = 2.76 TeV are presented. First results on p-Pb collisions at sqrt(s_NN) = 5.02 TeV are briefly reviewed.
Measurements of inclusive J/psi production in Pb-Pb collisions at sqrt(s_NN) = 2.76 TeV with the ALICE experiment  [PDF]
Antonin Maire,for the ALICE Collaboration
Physics , 2013,
Abstract: Charmonium is a prominent probe of the Quark-Gluon Plasma (QGP), expected to be formed in ultrarelativistic heavy-ion (A-A) collisions. It has been predicted that the J/psi(c-cbar) particle is dissolved in the deconfined medium created in A-A systems. However this suppression can be counterbalanced via regeneration of the charm/anti-charm bound state in QGP or via statistical production at the phase boundary. At LHC energies, the latter mechanisms are expected to play a more important role, due to a charm production cross section significantly larger than at lower energies. Measurements obtained by the ALICE experiment for inclusive J/psi production are shown, making use of Pb-Pb data at sqrt(s_NN) = 2.76 TeV, collected in 2010 and 2011. In particular, the focus is given on the nuclear modification factor, R_AA, derived for forward (2.5 < y < 4) and mid rapidities (|y| < 0.9), both down to zero transverse momentum (pT). The centrality, y and pT dependences of R_AA are presented and discussed in the context of theoretical models, together with PHENIX and CMS results.

Physics , 2013,
Abstract: The ALICE experiment has been running successfully since 2010 and made an impressive progress towards understanding of hot and dense QCD matter produced in heavy ion collisions at LHC energies. Recent results on identified particle spectra, azimuthal anisotropy, heavy flavour and quarkonium production in Pb-Pb collisions at sqrt(s_NN) = 2.76 TeV are presented. First results on p-Pb collisions and ALICE upgrade plans are briefly reviewed.
Heavy-flavour production in Pb-Pb collisions at the LHC, measured with the ALICE detector  [PDF]
Andrea Dainese,for the ALICE Collaboration
Physics , 2011, DOI: 10.1088/0954-3899/38/12/124032
Abstract: We present the first results from the ALICE experiment on the nuclear modification factors for heavy-flavour hadron production in Pb-Pb collisions at sqrt{s_NN}=2.76 TeV. Using proton-proton and lead-lead collision samples at sqrt{s}=7 TeV and sqrt{s_NN}=2.76 TeV, respectively, nuclear modification factors R_AA(pt) were measured for D mesons at central rapidity (via displaced decay vertex reconstruction), and for electrons and muons, at central and forward rapidity, respectively.
High p_T suppression of Lambda and K0s in Pb-Pb collisions at sqrt(s_NN)= 2.76 TeV with ALICE  [PDF]
Simone Schuchmann
Physics , 2011, DOI: 10.1088/0954-3899/38/12/124080
Abstract: The nuclear modification factors R_AA and R_CP of Lambda and K0s in Pb-Pb collisions at sqrt(s_NN)= 2.76 TeV measured by ALICE at LHC are presented. In central collisions a strong suppression at high p_T (p_T > 8 GeV/c) with respect to pp collisions is observed. The p_T region below is dominated by an enhancement of Lambda over the suppressed K0s. The results are compared to those for charged hadrons and to Lambda from lower collision energies.
