Neutron-Proton pairing and the Symmetry Energy in Nuclear Matter

ORAL

Abstract

The effect of neutron-proton(n-p) pairing in symmetry energy is studied in the symmetric matter. A separable n-p pairing interaction has been introduced by adjusting the pairing properties of the bare nucleon-nucleon interaction in the symmetric matter. The isospin triplet channel $T=1$ n-p pairing has small effect on the symmetry energy, but the effects of isospin singlet channel $T=0$ n-p pairing is significant especially at very low densities.
