A. Martinez et al., RADIATIVE-CORRECTIONS TO THE DALITZ PLOT OF SEMILEPTONIC DECAYS OF NEURAL BARYONS WITH LIGHT OR CHARM QUARKS (VOL 47, PG 3894, 1993), Physical review. D. Particles and fields, 50(3), 1994, pp. 2325-2328
We show that the radiative corrections containing terms up to order al
phaq/piM1 for unpolarized semileptonic decays of baryons with positron
emission can be obtained by simply reversing the sign of the axial-ve
ctor form factors in the corresponding final expressions of such decay
s with electron emission. This rule is valid regardless of the final k
inematical variables chosen and of the particular Lorentz frame in whi
ch the final results are required.
