Bremsstrahlung correction for baryon [Formula presented] decays in the four-body region of the Dalitz plot. II. Neutral baryons

A very accurate analytical expression and the corresponding numerical values for the bremsstrahlung of semileptonic decays of unpolarized neutral baryons, in the region of the Dalitz plot that covers the four-body events, is obtained. The same approach as the one considered for the charged baryons case is used here. These results contain all the terms of the order [Formula presented] times the momentum transfer. They are suitable for a model-independent experimental analysis, when high statistics decays of ordinary baryons as well as medium statistics decays of heavy quark baryons are considered.
