Description
We present the derived entropy formulas for finite reservoir systems, S(q), from universal thermostat independence and obtain the functional form of the corresponding generalized entropy-probability relation [1]. Our result interprets thermodynamically the subsystem temperature, T(1), and the index q in terms of the temperature, T , entropy, S , and heat capacity, C of the reservoir as and . In the infinite C limit, irrespective of the value of S , the Boltzmann-Gibbs approach is fully recovered. We apply this framework for the experimental determination of the original temperature of a finite thermostat, T , from the analysis of hadron spectra produced in high-energy collisions, by analyzing frequently considered simple models of the quark-gluon plasma.
