“…Fluctuations of thermodynamic quantities such as temperature and entropy have been proposed to give evidence for the existence of QGP phase transition and also provide direct insight into the properties of the system created in heavy-ion collisions [ 15,22]. Active study of event-by-event fluctuations in heavy-ion collisions was initiated by experiments at the SPS and now very much applied to the data at RHIC energies.…”

“…With the production of large number of particles in each of the collisions, it has become possible to extract thermodynamic quantities on an event-by-event basis, rather than averaging over a sample of events. Event-by-event fluctuations of ǫ, T , mean transverse momentum, particle multiplicity, particle ratios, etc., as well as fluctuations of conserved quantities within finite detector acceptances have been proposed to provide dynamical information regarding the evolving system [2,3,4,5,6,7,8,9,10,11,12].…”

We propose to characterize heavy-ion collisions at ultra-relativistic energies by using fluctuations of energy density and temperature. Temperature fluctuations on an event-by-event basis have been studied both in terms of global temperature of the event, and locally by constructing fluctuation maps in small phase space bins in each event. Global temperature fluctuations provide an estimation of the specific heat of the system. Local temperature fluctuations of the event may be ascribed to the remnants of initial energy density fluctuations. Together these two observables give an insight into the system created in heavy-ion collisions and its evolution. Event-by-event hydrodynamic calculations indeed provide adequate theoretical basis for understanding the origin of the fluctuations. We demonstrate the feasibility of studying global and local temperature fluctuations at the Large Hadron Collider energy by the use of AMPT event generator.

“…The study of fluctuations and correlations has been suggested as a useful means to reveal the mechanism of particle production and the formation of Quark-Gluon-Plasma (QGP) in the relativistic heavy-ion collisions [1,2]. Correlations and fluctuations of the thermodynamic quantities and/or the produced particle distributions could be significantly altered when the system undergoes phase transition because the degrees of freedom is largely different between the hadronic matter and the quark-gluon matter.…”

The parton rescattering effect on the charged hadron forward-backward multiplicity correlation in pp collisions at √ s=200 GeV is studied by a parton and hadron cascade model, PACIAE, based on the PYTHIA model. The calculated multiplicity and pseudorapidity distribution of the final state charged hadron are well compared with experimental data. It turned out that the final state charged hadron pseudorapidity distribution are different from the initial state charged partons. The parton rescattering effect on the charged hadron forward-backward multiplicity correlation increases with increasing parton rescattering strength in the center pseudorapidity region (|η| < 1). However, this effect becomes weaker in the outer pseudorapidity region (|η| > 1).
