Radiative corrections to the three-body region of the Dalitz plot of baryon semileptonic decays with angular correlation between polarized emitted baryons and charged leptons: The initial-baryon rest frame case

We complement the results for the radiative corrections to the ${\stackrel{^}{\mathbf{s}}}_{2}\ifmmode\cdot\else\textperiodcentered\fi{}\stackrel{^}{\mathbit{l}}$ angular correlation of baryon semileptonic decays of Neri et al. [Phys. Rev. D 78, 054018 (2008)] with the final results in the rest frame of the decaying baryon. In addition, we present an analytical result which was not possible to obtain in Neri et al.'s work.
