J. C. Jim\'enez, E. S. Fraga
TL;DR
This paper investigates the properties of lepton-rich cold quark matter in protoneutron stars using advanced perturbative QCD calculations, revealing constraints on stable strange quark matter due to neutrino effects.
Contribution
It introduces a detailed perturbative QCD framework for lepton-rich matter in protoneutron stars and analyzes how neutrino presence restricts stable strange quark matter.
Findings
Neutrino effects significantly alter the equation of state.
Stable strange quark matter has a more limited parameter space.
The study provides insights into the composition of protoneutron star matter.
Abstract
We explore protoneutron star matter in the framework of cold and dense QCD using the state-of-the-art perturbative equation of state including neutrinos fixed by a lepton fraction that is appropriate for this environment. Furthermore, we calculate the modifications in the lepton-rich equation of state showing that stable strange quark matter has a more restricted parameter space.
