Contribution

It introduces the gamma distribution form of work distribution for relativistic gases and links transverse energy fluctuations to the properties of the Quark-Gluon Plasma.

Findings

Work distribution is a gamma distribution with a unique shape parameter.

Transverse energy fluctuations depend on particle content during evolution.

Insights into Quark-Gluon Plasma properties from energy fluctuations.

Abstract

The work distribution of an expanding extreme relativistic gas is shown to be a gamma distribution with a different shape parameter as compared with its non-relativistic counterpart. This implies that the shape of the transverse energy distribution in relativistic heavy ion collisions depends on the particle contents during the evolution of the hot and dense matter. Therefore, transverse energy fluctuations provide additional insights into the Quark-Gluon Plasma produced in these collisions.
