Proton pairing in neutron stars

We studied the influence of dispersive self-energy effects, three-body forces, and polarization contributions to the interaction kernel on the S-1(0) proton pairing in neutron star matter. We found that a strong suppression of the gap by self-energy effects and three-body forces is at low density compensated by the attractive polarization interaction, shifting the domain of pairing to below rho(B)approximate to 0.3 fm(-3).
