Effects of meson mass decrease on superfluidity in nuclear matter

We calculate the 1S0 pairing gap in nuclear matter by adopting the “in-medium Bonn potential" proposed by Rapp et al. [e-print nucl-th/9706006], which takes into account the in-medium meson mass decrease, as the particle-particle interaction in the gap equation. The resulting gap is significantly reduced in comparison with the one obtained by adopting the original Bonn potential.
