H. Heiselberg (Nordita)
TL;DR
This paper investigates color superconductivity in quark matter within neutron stars, considering charge neutrality, beta equilibrium, and the effects of electron chemical potential and strange quark mass on pairing mechanisms.
Contribution
It provides a detailed analysis of how electron chemical potential and strange quark mass influence color superconductivity in neutron star matter, including mixed phases.
Findings
Electron chemical potential significantly affects pairing patterns.
Strange quark mass impacts the stability of color-flavor locked phases.
Mixed phases of quark and nuclear matter are feasible under certain conditions.
Abstract
Color superconductivity in quark matter is studied for electrically charge neutral neutron star matter in -equilibrium. Both bulk quark matter and mixed phases of quark and nuclear matter are treated. The electron chemical potential and strange quark mass affect the various quark chemical potentials and therefore also the color superconductivity due to dicolor pairing or color-flavor locking.
