An example of the interplay of nonextensivity and dynamics in the description of QCD matter

Abstract

Using a simple quasi-particle model of QCD matter, presented some time ago in the literature, in which interactions are modelled by some effective fugacities z, we investigate the interplay between the dynamical content of fugacities z and effects induced by nonextensivity in situations when this model is used in a nonextensive environment characterized by some nonextensive parameter q $\ne$ 1 (for the usual extensive case q=1). This allows for a better understanding of the role of nonextensivity in the more complicated descriptions of dense hadronic and QCD matter recently presented (in which dynamics is defined by a lagrangian, the form of which is specific to a given model).

Comments: accepted in EPJA 2016 the previous version (3) contained different work (with different title), was created by mistake and will shifted to arXiv:1810.07008 soon
