Quark contribution for center domain in heavy ion collisions

Abstract

The center domain structure is revisited with introduction of quark contribution to understand phenomenology in high-energy heavy ion collisions. We show the quark contribution may allow metastable states that would lead to a natural and consistent explanation for the temperature dependences of color opacity and viscosity. We also argue the possibility of indirect observations of the center domain structure in experiments due to a topological critical temperature.
