Skyrme model predictions for weak radiative decays of baryons

A Skyrme model calculation of weak radiative baryon decays is presented, based on a lagrangian describing weak non-leptonic 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 Σ+ → Pγ, where however the model involves substantial concellations among terms, which are sensitive to small changes of input parameters.
