Statistical thermal model analysis of particle production at LHC

KARASU UYSAL, Ayben | VARDAR, Necati

A successful description of the particle ratios measured in heavy-ion collisions has been achieved in the framework of thermal models. In such a way, a large number of observables can be reproduced with a small number of parameters, namely the temperature, baryo-chemical potential and a factor measuring the degree of strangeness saturation. The comparison of experimental data at and the model estimations has made possible to define the thermodynamic parameters of strongly interacting matter at chemical freeze-out temperature. The detailed study of hadron and meson production including resonanc ...Daha fazlası

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
