Pairing in high-density neutron matter including short- and long-range correlations

Understand

Pairing gaps in neutron matter need to be computed in a wide range of densities to address open questions in neutron star phenomenology.

• Traditionally, the Bardeen-Cooper-Schrieffer approach has been used to compute gaps from bare nucleon-nucleon interactions.
• Here, we incorporate the influence of short- and long-range correlations in the pairing gaps.
• Short-range correlations are treated including the appropriate fragmentation of single-particle states, and substantially suppress the gaps.
