Extracting kinetic freeze-out temperature and radial flow velocity from an improved Tsallis distribution

. We analyze the transverse-momentum (p T ) spectra of identified particles ( π ± , K ± , p , and p ¯ ) produced in gold-gold (Au-Au) and lead-lead (Pb-Pb) collisions over a s N N (center-of-mass energy per nucleon pair) range from 14.5 GeV (one of the Relativistic Heavy Ion Collider (RHIC) energies...
