Hadronic resonances, strange and multi-strange particle production in Xe-Xe and Pb-Pb collisions with ALICE at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

We present measurements of hadronic resonance, strange and multi-strange particle production in collisions of Xe-Xe and Pb-Pb at the center-of-mass energies of root s(NN) = 5.44 and 5.02 TeV, respectively, by the ALICE collaboration at the LHC. Particle ratios are presented as a function of multiplicity for K-s(0), Lambda, Xi(-), (Xi) over bar (+), Omega(-), (Omega) over bar (+), rho(770)(0), K{*}(892)(0), phi(1020) and Lambda(1520). Our results are discussed and compared with predictions of QCD-inspired event generators. Additionally, comparisons with lower energy measurements and smaller sys ...Daha fazlası

Higher moment fluctuations of identified particle distributions from ALICE

KARASU UYSAL, Ayben | ALICE Collaboration

Cumulants of conserved charges fluctuations are regarded as a potential tool to study the criticality in the QCD phase diagram and to determine the freeze-out parameters in a model-independent way. At LHC energies, the measurements of the ratio of the net-baryon (net-proton) cumulants can be used to test the lattice QCD predictions. In this work, we present the first measurements of cumulants of the net-proton number distributions up to 4th order in Pb-Pb collisions at root s(NN) = 2.76 and 5.02 TeV as a function of collision centrality. We compare our cumulant ratios results with the STAR exp ...Daha fazlası

The evolution of the near-side peak in two-particle number and transverse momentum correlations in Pb-Pb collisions from ALICE

KARASU UYSAL, Ayben | ALICE Collaboration

Two-particle number and transverse momentum correlations are powerful tools for studying the medium produced in heavy-ion collisions. Correlations in the angular separation of pairs of hadrons can provide information on the medium transport characteristics. In particular, the transverse momentum correlations are sensitive to momentum currents, and provide information about the system life time, the shear viscosity over entropy density ratio (eta/s) and the system relaxation time (tau(pi)). Furthermore, the interaction of the jets produced in the initial stages of a collision can be studied usi ...Daha fazlası

Exploring jet profiles in Pb-Pb collisions at 5.02 TeV with the ALICE detector

KARASU UYSAL, Ayben | ALICE Collaboration

In this contribution, we present measurements of inclusive jet production with the ALICE detector in Pb-Pb collisions at root s(NN) = 5.02 TeV. Production cross sections of charged particle jets and fully reconstructed jets are measured with jet resolution parameters R = 0.2 and 0.3. To quantify the medium induced parton energy loss, jet nuclear modification factors (R-AA) are measured by utilizing POWHEG+Pythia8 predictions as reference cross section in pp collisions. We also calculate the ratio of jet production cross sections for jets reconstructed with different cone radii to explore the j ...Daha fazlası

Light (anti-)nuclei production and elliptic flow at the LHC with ALICE

KARASU UYSAL, Ayben | ALICE Collaboration

Results on the production of stable light nuclei, including deuterons, He-3, He-4 and the corresponding anti-nuclei, in Pb-Pb collisions at root s(NN) = 2.76 TeV and root s(NN) = 5.02 TeV are presented and compared with theoretical predictions and with the results in small systems to provide insight into the production mechanisms of (anti-)nuclei at colliders. The experimental results are presented giving a critical view of their comparison to the expectations from coalescence and hydrodynamic models that aim at describing both the p(T)-spectra and the elliptic flow.

Muon physics at forward rapidity with the ALICE detector upgrade

KARASU UYSAL, Ayben | ALICE Collaboration

ALICE is the experiment specifically designed to study the Quark-Gluon Plasma (QGP) in heavy-ion collisions at the CERN LHC. The ALICE detector will be upgraded during the Long Shutdown 2, planned for 2019-2020, in order to cope with the maximum interaction rate of 50 kHz of Pb-Pb collisions foreseen for Runs 3 and 4. The ambitious programme of high-precision measurements, expected for muon physics after 2020, requires an upgrade of the front-end and readout electronics of the existing Muon Spectrometer. This concerns the Cathode Pad Chambers (CPC) used for tracking and the Resistive Plate Cha ...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.
