MSW effect with quark matter: Neutron Star as a case study

Abstract

With the recent findings from various astrophysical results hinting towards possible existence of strange quark matters with the baryonic resonances such as ${\Lambda }^0,{\Sigma }^0,\Xi ,\Omega$ in the core of neutron stars, we investigate the MSW effect, in general, in quark matter. We find that the resonance condition for the complete conversion of down-quark to strange quark requires estremely large matter density ($ρ_u \simeq 10^{5}\,\mbox{fm}^{-3} $). Nonetheless the neutron stars provide a best condition for the conversion to be statistically significant which is of the same order as is expected from imposing charge neutrality condition. This has a possibility of resolving the hyperon puzzle as well as the equation of state for dense baryonic matter.
