摘要

It is shown that the freezeout parameters estimated in the heavy-ion collisions all are well described by a constant value of the entropy density ss divided by T3T^3. The value of s/T3s/T^3 has been taken from the lattice QCD simulations at zero baryo-chemical potential μB\mu_B and assumed to remain constant for finite μB\mu_B. This implies that the hadronic matter in rest frame of produced system can be determined by constant degrees of freedom. Furthermore, this condition has been used to predict the freezeout parameters at low temperatures.
