Abstract

We perform a Taylor series expansion of Tsallis distribution by assuming the Tsallis parameter qq close to 1. The qq value shows the deviation of a system from a thermalised Boltzmann distribution. By taking up to first order in (q1)(q-1), we derive an analytical result for Tsallis distribution including radial flow. Further, in the present work, we also study the speed of sound (csc_s) as a function of temperature using the non-extensive Tsallis statistics for different qq values and for different mass cut-offs.
