The role of pomeron states in the Glueball Resonance Gas

Abstract

In this note, we present our recent analyses of the thermodynamic properties of the glueball resonance gas. We observe that the dominant contribution to the thermodynamic quantities, such as pressure, trace anomaly, and entropy, is coming from the free glueball gas with the states of positive charge conjugation (i.e., pomeron). A comparison of pomeron states obtained from LQCD and functional methods within the glueball resonance gas model is also presented.
