Deconfinement transition in protoneutron star cores: Analysis within the MIT Bag model

TL;DR

This paper investigates how color superconductivity influences the transition from hadronic to quark matter in protoneutron star cores, using the MIT Bag model and comparing with NJL model results.

Contribution

It introduces a detailed analysis of the deconfinement transition considering color superconductivity within the MIT Bag model, including a comparison with NJL model outcomes.

Findings

Color superconductivity affects the transition conditions.

Comparison shows differences between MIT Bag and NJL models.

Results highlight the role of trapped neutrinos in the transition.

Abstract

We analyze the effect of color superconductivity in the transition from hot hadron matter to quark matter in the presence of a gas of trapped electron neutrinos. We adopt a two-phase picture in which the hadronic phase is described trough a nonlinear Walecka model and just deconfined matter through the MIT bag model including color superconductivity. We compare the present results with those obtained within the NJL model.
