Abstract

We investigate the interplay between the pion exchanges and the contact interactions in the S-1(0) channel using a N4LO chiral potential. We compute the pairing gap without the pions and show that, although the contact interactions dominate in this channel, the gap is strongly enhanced without the attraction that comes from the pions.
