1S0 Proton and Neutron Superfluidity in beta-stable Neutron Star Matter

Abstract

We investigate the effect of a microscopic three-body force on the proton and neutron superfluidity in the ${}^1{S}_0$ channel in ${\hat{I}}^2$-stable neutron star matter. It is found that the three-body force has only a small effect on the neutron ${}^1{S}_0$ pairing gap, but it suppresses strongly the proton ${}^1{S}_0$ superfluidity in ${\hat{I}}^2$-stable neutron star matter.
