△contribution to the parity-violating nucleon-nucleon force

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.
