A. Martinez et al., RADIATIVE-CORRECTIONS TO THE DALITZ PLOT OF SEMILEPTONIC DECAYS OF NEUTRAL BARYONS WITH LIGHT OR CHARM QUARKS, Physical review. D. Particles and fields, 47(9), 1993, pp. 3984-3993
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.
