Non-linear flow modes of identified particles in Pb-Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The pT-differential non-linear flow modes, v4,22, v5,32, v6,33 and v6,222 for π ±, K±, K0 S , p + p, Λ + Λ and φ-meson have been measured for the first time at √ sNN = 5.02 TeV in Pb-Pb collisions with the ALICE detector at the Large Hadron Collider. The results were obtained with a multi-particle technique, correlating the identified hadrons with reference charged particles from a different pseudorapidity region. These non-linear observables probe the contribution from the second and third order initial spatial anisotropy coefficients to higher flow harmonics. All the characteristic features ...Daha fazlası

Energy dependence of φ(1020) production at mid-rapidity in pp collisions with ALICE at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

Hadronic resonances are unique tools to investigate the interplay of re-scattering and regeneration effects during the hadronization phase in heavy-ion collisions. Measurements in small collision systems provide a necessary baseline for heavy-ion data, help to tune pQCD inspired event generators and give insight into the search for the onset of collective effects. As the phi meson has a longer lifetime compared to other resonances, it is expected that its production would be much less affected by regeneration and re-scattering processes. We report on measurements of phi meson production in min ...Daha fazlası

Heavy-flavour hadron decay leptons in Pb-Pb and Xe-Xe collisions at the LHC with ALICE

KARASU UYSAL, Ayben | ALICE Collaboration

Heavy quarks, i.e. charm and beauty, are sensitive probes of the medium produced in high-energy heavy-ion collisions. They are produced in the early stage of the collision, mainly in hard partonic scattering processes, and are expected to experience the whole collision evolution interacting with the medium constituents via both elastic and inelastic processes. The nuclear modification factor (R-AA) is one of the main experimental observables that allow us to investigate the interaction strength of heavy quarks with the medium. The ALICE collaboration measured the production of open heavy-flavo ...Daha fazlası

Measurements of heavy-flavour correlations and jets with ALICE at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

In this work, the latest heavy-flavour correlation and jet measurements at mid-rapidity with the ALICE detector in pp, p-Pb and Pb-Pb collisions from the LHC Run 2 are reported. In particular, the results of azimuthal correlation measurements of D mesons with charged particles in pp collisions at root s = 13 TeV and in p-Pb collisions at root S-NN = 5.02 TeV are presented. Studies on the centrality-dependent azimuthal correlations of heavy-flavour hadron decay electrons with charged particles in Pb Pb collisions at root S-NN = 5.02 TeV are shown. In addition, measurements of D-meson tagged jet ...Daha fazlası

Addendum: Centrality dependence of high-pT D-meson suppression in Pb–Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

This is an addendum to the article JHEP 11 (2015) 205 [1]. The figures 3 (right), 4 (right) and 5 are updated with published results on non-prompt J/ψ-meson production from the CMS collaboration.

KARASU UYSAL, Ayben | ALICE Collaboration

The transverse momentum distributions of the strange and double-strange hyperon resonances ( Sigma ( 1385)(+/-), Xi ( 1530)(0)) produced in p-Pb collisions at root s(NN) = 5.02 TeV were measured in the rapidity range -0.5 < yCMS < 0 for event classes corresponding to different charged-particle multiplicity densities, < dN(ch)/d eta(lab)> . The mean transverse momentumvalues are presented as a function of < dNch/d eta(lab)>, as well as a function of the particle masses and compared with previous results on hyperon production. The integrated yield ratios of excited to ground- state hyperons are ...Daha fazlası

Quarkonium measurements in nucleus-nucleus collisions with ALICE

KARASU UYSAL, Ayben | ALICE Collaboration

Quarkonia, i.e. bound states of b (b) over bar and c (c) over bar quarks, are powerful observables to study the properties of nuclear matter under extreme conditions. The formation of a Quark-Gluon Plasma (QGP), which is predicted by lattice QCD calculations at high temperatures as reached at the LHC energies, has a strong influence on the production and behavior of quarkonia. The latest ALICE results on bottomonium and charmonium production in nucleus-nucleus collisions are presented. This includes measurements of the gamma(1S) and gamma(2S) nuclear modification factor (R-AA) at forward rapid ...Daha fazlası

f0(980) resonance production in pp collisions with the ALICE detector at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

We report on a preliminary study of the production of f(0)(980) -> pi(+)pi(-) at mid-rapidity (vertical bar y vertical bar < 0.5) performed with the ALICE detector at the LHC in minimum bias pp collisions at the centre-of-mass energy root s = 5.02 TeV. The f(0)(980) signal extraction is challenging due to the large background from correlated pi(+)pi(-) pairs from other resonance decays in the invariant mass window under study, as well as due to the combinatorics from uncorrelated pairs. We present the strategy for the signal extraction and first results in terms of p(T)-dependent production yi ...Daha fazlası

Quarkonium production in p-Pb collisions with ALICE

KARASU UYSAL, Ayben | ALICE Collaboration

ALICE has measured quarkonium production in p-Pb collisions at backward (-4.46 < y(cms) < 2.96), mid (-1.37 < y(cms) < 0.43) and forward (2.03 < y(cms) < 3,53) rapidity (y) regions down to zero transverse momentum (p(T)). The inclusive J/psi production has been studied at mid-y in p-Pb interactions at root S-NN = 5.02 TeV and at forward and backward y in p-Pb collisions at root S-NN = 5.02 TeV and 8.16 TeV. The comparison of the J/psi production to the one of the loosely bound psi(2S) state is discussed, together with new results on the nuclear modification factors of the gamma(1S) and gamma(2 ...Daha fazlası

Measurements of the chiral magnetic effect in Pb-Pb collisions with ALICE

KARASU UYSAL, Ayben | ALICE Collaboration

We present the measurement of the charge-dependent 3-particle azimuthal correlation for unidentified charged particles in Pb-Pb collisions at root S-NN = 5.02 TeV in ALICE. The results are compared with corresponding results from Pb-Pb collisions at root S-NN = 2.76 TeV. We observe no significant difference in the charge-sensitive 3-particle correlator (gamma(112)) between the two collision energies. Charged-dependent mixed-harmonic correlator (gamma(132)) is also presented and compared with the predictions from a blast-wave model incorporating local charge conservation.
