Thermodynamics of the low density excluded volume hadron gas

Understand

We consider thermodynamics of the excluded volume particles at finite temperature and chemical potential, in the low density approximation.

• We assume Boltzmann statistics and study the influence of the excluded volume on an ideal gas thermodynamics at the same temperature, pressure and numbers of particles.
• We show, that considering the change of the free enthalpy due to the excluded volume, and using the Maxwell identities, one can derive relevant thermodynamic functions and parameters of multi-component gases.
• The derivation is quite general as particles may have different sizes and shapes which can also depend on their momenta.
