摘要：

Because of the near future work of the NA48 experimental group, we have calculated the radiative corrections (RC) to the Dalitz plot of baryon semileptonic decays with angular correlation between polarized emitted baryons and charged leptons. This work covers the two cases, charged and neutral decaying baryons, and it is restricted to the so called three body region of the Dalitz plot. Also it is specialized at the c.m. frame of the emitted baryon. We consider terms up to (alpha/Pi)(q/M-1)(0), where q is the momentum transfer and M, is the mass of the decaying baryon, and neglect terms of the order (alpha/Pi)(q/M-1)(n), n=1,2,.... The analytical expressions displayed are ready to obtain numerical results, suitable for a model-independent experimental analysis.
