We reformulate the analysis of nuclear parity violation (PV) within the framework of effective field theory (EFT). To O(Q), the PV nucleon–nucleon (NN) interaction depends on five a priori unknown constants that parameterize ...

We show that the tail of the chiral two-pion exchange nucleon-nucleon potential is proportional to the pion-nucleon (pN) scalar form factor and discuss how it can be translated into effective scalar meson interactions. We ...
