Weak Radiative Baryon Decays of the Skyrme Model.
A Skyrme model calculation of weak radiative baryon octect and decuplet decays is presented, based on a Lagrangian describing weak nonleptonic decays of mesons previously discussed by Donoghue, et al. There are no free parameters in the Skyrme model predictions for weak radiative decays, as all necessary parameters are obtained from other contexts. The predictions of the Skyrme model for the weak radiative baryon decays are in good agreement with experiment, except for (SIGMA)('+) (--->) P(,(gamma)), where however the model involves substantial cancellations among terms, which are sensitive to small changes of input parameters.
