BREMSSTRAHLUNG CORRECTION FOR BARYON BETA-DECAYS IN THE 4-BODY REGIONOF THE DALITZ PLOT - CHARGED BARYONS

The analytical formula and the corresponding numerical results for the bremsstrahlung of semileptonic decays of charged baryons, in the regi on of the Dalitz plot that covers the four-body events which were not considered in previous calculations, are obtained. The formula is very accurate because it includes all the terms of the order cu times the momentum transfer. The model dependence of the radiative correction is kept in a general form which is suitable for a model-independent expe rimental analysis. The bremsstrahlung contribution in terms of the ene rgies of the produced fermions is obtained by analytical means. Our re sult is suitable for high statistics decays of ordinary baryons as wel l as for medium statistics decays of charm baryons.
