Confinement/Deconfinement temperature for a rotating quark-gluon plasma

High Energy Physics - Theory 2022-05-25 v2

Abstract

Non-central heavy ion collisions lead to the production of a quark gluon plasma with angular momentum. We investigate, using holographic AdS/QCD models, how does rotation of the medium affects the confinement/deconfinement transition temperature TcT_c. In holographic models, this transition is represented by a Hawking-Page process involving two asymptotically anti-de Sitter spaces. The plasma is represented here by extending the holographic approach to anti-de Sitter spaces with cylindrical symmetry. Then, the rotation of the medium is introduced through a Lorentz boost. We consider hard and soft wall AdS/QCD models. In both cases we find it out that, as the rotational velocity vv increases, TcT_c decreases, following the expression Tc(v)=Tc(0)/γ(v)T_c(v) = T_c(0)/\gamma(v), where γ(v)\gamma(v) is the Lorentz factor.
