摘要:
The thermodynamic properties of charged particles, such as the energy density, pressure, entropy density, particle density, and squared speed of sound at the kinetic freeze-out in the $$\mathrm {Au+Au}$$ collisions from the relativistic heavy ion collider (RHIC) beam energy scan program ( $$\sqrt{s_\text {NN}}$$ = 7.7–200 GeV) and in the $$\mathrm {Cu + Cu}$$ collisions at $$\sqrt{s_\text {NN}}$$ = 62.4, 200 GeV are studied using the thermodynamically consistent Tsallis distribution. The energy densit...
