Hadron Mass Scaling in Regge Phenomenology

Abstract

We show that Regge phenomenology is consistent with the only universal scaling law for hadron masses, M^\ast /M=(α^{&#39;}/α^{&#39;\ast})^{1/2}, where asterisk indicates a finite-temperature quantity. Phenomenological models further suggest the following expression of the above scaling in terms of the temperature-dependent gluon condensate: M^\ast / M = (α^&#39;/α^{&#39;\ast})^{1/2} = (<G_{μν}^a>^\ast/<G^{aμν}>)^{1/4}.
