Beth-Uhlenbeck approach for repulsive interactions between baryons in a hadron gas
Beth-Uhlenbeck approach for repulsive interactions between baryons in a hadron gas
The quantum mechanical Beth-Uhlenbeck (BU) approach for repulsive hard-core interactions between baryons is applied to the thermodynamics of a hadron gas. The second virial coefficient $a_2$ -- the "excluded volume" parameter -- calculated within the BU approach is found to be temperature dependent, and it differs dramatically from the classical …
