Description
We consider the renormalization group optimized perturbation theory (RGOPT) at next-to-next-to-leading order (NNLO) to evaluate the equation of state (EoS) for cold quark matter, incorporating full strange quark mass dependence. RGOPT entails an all-order RG resummation that generically reduces the renormalization scale uncertainties as compared to perturbative QCD (pQCD). We obtain mass-radius relations for pure quark stars and compare results with pQCD predictions. We also consider more general EoS for hybrid stars, with our approach implemented for the quark matter contribution.
