| Descripción |
A survey of pairing properties of nucleonic matter is presented that includes
the off-shell propagation associated with short-range and tensor correlations.
For this purpose, the gap equation has been solved in its most general form
employing the complete energy and momentum dependence of the normal self-energy
contributions. The latter correlations include the self-consistent calculation
of the nucleon self-energy that is generated by the summation of ladder
diagrams. This treatment preserves the conservation of particle number unlike
approaches in which the self-energy is based on the Brueckner-Hartree-Fock
approximation. A huge reduction in the strength as well as temperature and
density range of ${}^3S_1$-${}^3D_1$ pairing is obtained for nuclear matter as
compared to the standard BCS treatment. Similar dramatic results pertain to
${}^1S_0$ pairing of neutrons in neutron matter.
