³PF₂ neutron superfluidity in neutron stars and three-body force effect

We investigate the ³PF₂ neutron superfluidity in \beta-stable neutron star matter and neutron stars by using the BCS theory and the Brueckner--Hartree--Fock approach. We adopt the Argonne V₁₈ potential supplemented with a microscopic three-body force as the realistic nucleon--nucleon interaction. We have concentrated on studying the three-body force effect on the ³PF₂ neutron pairing gap. It is found that the three-body force effect is to enhance remarkably the ³PF₂ neutron superfluidity in neutron star matter and neutron stars.
