Decays of 1/2^- baryons in chiral effective theory

We construct an SU(3)(L) x SU(3)(R) symmetric chiral effective model which includes parity pair baryon fields. It is assumed that the positive and negative parity baryons in the parity pair have opposite chiral transformation properties than each other. Using this model, strong decays of the negative parity baryons are studied up to the o...更多
