Entropy analysis in relativistic ion-ion collisions

Processes in which particles are produced may be regarded as the so called dynamical systems. Investigations involving the local entropy produced in relativistic nucleus-nucleus (AA) collisions are expected to provide direct information about the internal degrees of freedom of the QGP medium and its evolution. It has been suggested that event coincidence probability method of measuring entropy as proposed by Ma is well suited for the analysis of local properties in multiparticle system produced in high energy collisions. This method is applicable to both hadron-hadron and nucleus-nucleus collisions. In AA collisions, entropy measurement can be used not only to search for QGP formation but it may also serve as an additional tool to study the correlations and event-by-event (ebe) fluctuations
