RADIATIVE-CORRECTIONS TO THE DALITZ PLOT OF SEMILEPTONIC DECAYS OF NEUTRAL BARYONS WITH LIGHT OR CHARM QUARKS

In this paper we obtain an expression for the Dalitz plot of semilepto nic decays of neutral baryons including radiative corrections up to or der alphaq/piM1 (q is the four-momentum transfer and M1 is the mass of the decaying baryon). The model dependence of the radiative correctio ns is kept in a general form which is suitable for a model-independent experimental analysis. The bremsstrahlung contribution is given in tw o ways. The first one leaves the triple integration over the photon va riables to be performed numerically and the second one is completely a nalytic. Our result is suitable for high-statistics decays of ordinary baryons as well as for medium-statistics decays of charm baryons.
