Erratum to: Insight into particle production mechanisms via angular correlations of identified particles in pp collisions at √s = 7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We have identified a mistake in how Fig. 1 is referenced in the text of the article Eur. Phys. J. C 77 (2017) no. 8, 569 which affected three paragraphs of the results section. The corrected three paragraphs as well as the unmodified accompanying figure are reproduced in this document with the correct labeling. In addition, an editing issue led to a missing acknowledgements section. The missing section is reproduced at the end of this document in the manner in which it should have appeared in the published article.

Technical Design Report for the Upgrade of the ALICE Inner Tracking System

KARASU UYSAL, Ayben | ALICE Collaboration

ALICE (A Large Ion Collider Experiment) is studying the physics of strongly interacting matter, and in particular the properties of the Quark–Gluon Plasma (QGP), using proton–proton, proton–nucleus and nucleus–nucleus collisions at the CERN LHC (Large Hadron Collider). The ALICE Collaboration is preparing a major upgrade of the experimental apparatus, planned for installation in the second long LHC shutdown in the years 2018–2019. A key element of the ALICE upgrade is the construction of a new, ultra-light, high-resolution Inner Tracking System (ITS) based on monolithic CMOS pixel detectors. T ...Daha fazlası

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

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

Production of hadronic resonances at LHC energies with the ALICE experiment

KARASU UYSAL, Ayben | ALICE Collaboration

Hadronic resonances are strongly decaying particles with extremely short lifetimes of about few fm/c, which are comparable to or smaller than the lifetime of the system formed in relativistic collisions. Due to their short lifetimes, resonance particles can be used to investigate the freeze-out mechanisms after hadronization. This contribution summarizes the results of resonance particle productions measured by the ALICE collaboration at LHC from various colliding systems and energies. Measured mass, width, transverse momentum and particle ratios of those resonances have been reported. Theoret ...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.

Inclusive quarkonium production at forward rapidity in pp collisions at √s = 8 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We report on the inclusive production cross sec- tions of J/ψ , ψ (2S), Υ (1S), Υ (2S) and Υ (3S), measured at forward rapidity with the ALICE detector in pp colli- sions at a center-of-mass energy √s = 8 TeV. The analy- sis is based on data collected at the LHC and corresponds to an integrated luminosity of 1.23 pb−1. Quarkonia are reconstructed in the dimuon-decay channel. The differen- tial production cross sections are measured as a function of the transverse momentum pT and rapidity y, over the pT ranges0< pT

Jet-hadron correlations measured relative to the second order event plane in Pb-Pb collisions at sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The quark gluon plasma produced in ultrarelativistic heavy-ion collisions at the Large Hadron Collider (LHC) can be studied by measuring the modifications of jets formed by hard scattered partons which interact with the medium. We studied these modifications via angular correlations of jets with charged hadrons for jets with momenta 20 < p jet T < 40 GeV/c as a function of the associated particle momentum. The reaction plane fit method is used in this analysis to remove the flow modulated background. The analysis of angular correlations for different orientations of the jet relative to the sec ...Daha fazlası

Z-boson production in p-Pb collisions at √sNN = 8.16 TeV and Pb-Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Measurement of Z-boson production in p-Pb collisions at √ sNN = 8.16 TeV and Pb-Pb collisions at √ sNN = 5.02 TeV is reported. It is performed in the dimuon decay channel, through the detection of muons with pseudorapidity −4 < ηµ < −2.5 and transverse momentum p µ T > 20 GeV/c in the laboratory frame. The invariant yield and nuclear modification factor are measured for opposite-sign dimuons with invariant mass 60 < mµµ < 120 GeV/c 2 and rapidity 2.5 < yµµ cms < 4. They are presented as a function of rapidity and, for the Pb-Pb collisions, of centrality as well. The results are compared with t ...Daha fazlası

Production of ω mesons in pp collisions at √s = 7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The invariant differential cross section of inclusive ω(782) meson production at midrapidity (|y| < 0.5) in pp collisions at √s = 7 TeV was measured with the ALICE detector at the LHC over a transverse momentum range of 2 < pT < 17 GeV/c. The ω meson was reconstructed via its ω → π+π−π0 decay channel. The measured ω production cross section is compared to various calculations: PYTHIA 8.2 Monash 2013 describes the data, while PYTHIA 8.2 Tune 4C overestimates the data by about 50%. A recent NLO calculation, which includes a model describing the fragmentation of the whole vector-meson nonet, desc ...Daha fazlası
