Contact interaction in the nonrelativistic pion absorption operator

Nuclear Theory 2007-05-23 v1

Abstract

Chirally invariant Lagrangian containing nucleon, pion and chiral scalar fields is considered. A consistent scheme is proposed for obtaining the nonrelativistic operator of pion absorption by NN-pair taking into account the chiral scalar exchange. An important role of the contact interaction is pointed out.D
