We present an overview of the calculation of radiative corrections to the Dalitz plot of baryon semileptonic decays with angular correlation between polarized emitted baryons and charged leptons. We discuss both charged and neutral decaying baryons, restricted to the three-body region of the Dalitz plot. Our analysis is specialized to cover two possible scenarios: The center-of-mass frames of the emitted and the decaying baryons. We have accounted for terms up to order ({alpha}/{pi})(q/M{sub 1}){sup 0}, where q is the momentum-transfer and M{sup 1} is the mass of the decaying baryon, and neglected terms of order ({alpha}/{pi})(q/M{sub 1}){sup n} for n{>=}1. The expressions displayed are ready to obtain numerical results, suitable for model-independent experimental analyses.
