At star experiment, average sfficiency of positively and negatively charged particles had been used for cumulants calculation because of thge small efficiency difference between positively and negatively charged particles. However, there is finite difference in the detecting efficiency for positively and negatively charged hadrons. The difference is also dependent on collision energy. In...

Phase transitions and/or critical phenomena are known to lead to local density fluctuations. In the coalescence mechanism of particle production, the baryon formation probability can be influenced by these local parton density fluctuations, thereby leading to clusters and voids in the phase-space distribution of hadrons. In order to probe the density fluctuation in heavy ion collisions, we...

Critical phenomena in quantum chromodynamics (QCD) have been attracting attention to find features of chiral symmetry breaking (or restoration) in QCD. QCD critical point (CP) is one of the cornerstones to deduce the QCD phase structure. Theoretically, higher than 3rd order cumulants can be negative [1] due to Z(2) criticality around CP [2] and the remnant effect of O(4) criticality in the...

Experiments at RHIC and LHC are on the quest to unearth the nature of the QCD phase transition and to get a glimpse of how matter behaves at such extreme conditions. Phase transitions are governed by a set of thermodynamic parameters, like, temperature ($T$), pressure, entropy and energy density ($E$), and can be further characterized by their response functions, like, specific...

A thermodynamically consistent form of the Tsallis distribution at $y$ = 0 has been used for fitting the transverse momentum spectra $d^{2}N/dydp_{T}$ and to study the yields of particles measured by the ALICE and CMS experiments at the CERN Large Hadron Collider (LHC). The Tsallis distribution describes the $p_{T}$ spectra very
well. The values of $dN/dy|_{y=0}$ obtained from the Tsallis...
