Provided a parameter-free formulation within chiral effective field theory.
Enhanced understanding of parity violation in nucleon interactions.
Abstract
Because the nucleon may be excited and transformed into a virtual resonance easily, we consider the decuplet contribution to the parity-violating (PV) nucleon-nucleon interaction in the chiral effective field theory. The effective PV nucleon-nucleon potential is derived without introducing any unknown coupling constants.
