The two-wave quark production scenario, proposed by Scott Pratt in 2012 as a signature of the production of quark-gluon plasma in high energy heavy ion collisions, can be studied with balance functions of identified particle pairs. We present measurements of such balance functions based on an analysis of data acquired at the Large Hadron Collider (LHC) by the ALICE detector. Balance functions...
Radiation of photons is a promising and efficient tool to study the initial state of heavy-ion collisions. Unlike hadrons, photons are emitted during all stages of the expanding fireball and, due to their electromagnetic nature, they do not suffer further interaction with the medium, carrying undistorted information about the circumstances of their production. In this talk we discuss spectrum...
ATLAS measurements of correlations between particle pairs in relative azimuthal angle (Δϕ) and pseudorapidity separation (Δη), in pp collisions at √s=2.76, 5.02 and 13~TeV, and in p+Pb collisions at √sNN=5.02~TeV are presented. Prior measurements have shown that in pp collisions with a large multiplicity of produced particles, a long-range structure,commonly called the ``ridge'', develops...
Measurements obtained in high-multiplicity proton-proton (pp) and proton-lead (p--Pb) collisions at the Large Hadron Collider have exhibited features that are similar to what was observed in lead-lead (Pb--Pb) collisions, where they are usually interpreted as signs of collective behaviour.
These observations warrant a comprehensive study of the production of identified particles which are...
The spinodal instability of a baryon-rich quark matter is studied in both the Nambu-Jona-Lasino (NJL) and the Polyakov-Nambu-Jona-Lasino (PNJL) model. We first obtain via the linear response theory the boundary of the spinodal region and calculate the growth rate of unstable modes. We find that at the mean-field level, the boundary of spinodal instability shrinks with the wave number of...
