Curing the acausal behavior of the sound velocity in an excluded volume hadron resonance gas model

We improve the excluded volume hadron resonances gas model (EHRG) to cure the acausal behavior of the sound velocity which is typical of excluded volume models. We achieve this by including temperature (T) and density ({\mu}) dependent hadron masses in the partition function of EHRG. The temperature...
