Chiral Susceptibility in Hard Thermal Loop Approximation
Purnendu Chakraborty🇮🇳 · Munshi G. Mustafa🇮🇳 · Markus H. Thoma🇩🇪
Abstract
The static and dynamic chiral susceptibilities in the quark-gluon plasma are calculated within the lowest order perturbative QCD at finite temperature and the Hard Thermal Loop resummation technique using an effective quark propagator. After regularisation of ultraviolet divergences, the Hard Thermal Loop results are compared to QCD lattice simulations.
