Using the Beth–Uhlenbeck Approach to Describe the Kaon to Pion Ratio in a 2 + 1 Flavor PNJL Model
The kaon to pion ratios are discussed in the framework of a 2 + 1 flavor PNJL model. In order to interpret the behavior of bound states in medium, the Beth−Uhlenbeck approach is used. It is shown that, in terms of phase shifts in the <inline-formula> <math display="inline&quo...
