Dielectron measurements in pp and Pb-Pb colllisions with ALICE at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

The production of low-mass dielectrons is one of the most promising tools for the investigation of chiral symmetry restoration and thermal radiation from the QGP created in heavy-ion collisions. To single out the signal characteristics of the QGP, it is crucial to understand the primordial e+e− pair production in vacuum, i.e. in inelastic proton-proton (pp) collisions. Low-mass dielectrons have been measured with ALICE at the LHC in pp collisions at √s = 7 and 13 TeV, and in Pb–Pb collisions at √sNN = 2.76 TeV. An overview of the results on dielectron production is presented, together with the ...Daha fazlası

Exploring the Phase Space of Jet Splittings at ALICE using Grooming and Recursive Techniques

KARASU UYSAL, Ayben | ALICE Collaboration

Hard splittings in the evolution of a hard scattered parton may be modified by the presence of a dense strongly interacting medium. Grooming procedures can be used to isolate such hard components of a jet and allows one to focus on the two subjets resulting from a sufficiently hard partonic splitting. Measurements of the symmetry parameter (z(g)), angular separation (R-g) and number of splittings (n(SD)) of Soft Drop groomed jets are reported as measured with the ALICE Detector in pp and Pb-Pb collisions at root s = 7 TeV and root s(NN) = 2.76 TeV, respectively. The use of recursive splittings ...Daha fazlası

Measurement of prompt D0, D+, D∗+, and D+s production in p–Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The measurement of the production of prompt D0, D+, D∗+, and D+s mesons in proton–lead (p–Pb) collisions at the centre-of-mass energy per nucleon pair of √sNN = 5.02 TeV, with an integrated luminosity of 292 ± 11 μb−1, are reported. Differential pro- duction cross sections are measured at mid-rapidity (−0.96 < ycms < 0.04) as a function of transverse momentum (pT) in the intervals 0 < pT < 36 GeV/c for D0, 1 < pT < 36 GeV/c for D+ and D∗+, and 2 < pT < 24GeV/c for D+s mesons. For each species, the nuclear modification factor RpPb is calculated as a function of pT using a proton-proton (pp) ref ...Daha fazlası

Constraining production models with light (anti-)nuclei measurements in small systems with ALICE at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

The production of deuterons and anti-deuterons in pp collisions at root s = 7 and 13 TeV has been studied as a function of charged-particle multiplicity using the ALICE detector at the LHC. The preliminary results are shown here, together with those obtained in heavy-ion collisions. They are presented by focusing the discussion on the comparison with expectations from hadron-coalescence models.

Recent resonance results measured with the ALICE detector at the LHC

YALÇIN, Serpil | KARASU UYSAL, Ayben | ALICE Collaboration

Resonances are extremely short lived particles (τ ∼ 10-23 s). Due to their lifetime, they may decay, re-scatter and regenerate between chemical and kinetic freeze-outs. For this reason, they are very significant probes to understand the evolution of the medium and particle production mechanism in heavy ion collisions. Different than other particles, resonance properties such as mass, width and yield can be modified by the medium created in the relativistic collisions. Moreover, comparison of resonances produced in different collisions provide evidences about possible in medium effects and syst ...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
