The beta decay of free quarks is studied in the framework of the standard SU(2) x U(1) model of weak and electromagnetic interactions. The so-called 'weak' part of radiative corrections is evaluated to order alpha in one-loop approximation using a renormalization scheme, which adjusts the counter terms to the electric charge, and to the mass of the charged and neutral vector bosons, Msub(w) and Msub(o), respectively. The obtained result is, to a good approximation, equal with the 'weak' part of radiative corrections for the semileptonic decay of any hyperon. It is shown in the model that the methods, which work excellently in case of the 'weak' corrections, do not, in general, provide us with the dominant part of the 'photonic' corrections.

In this paper the G/sub E/ and G/sub M/ form factors of the proton and neutron are calculated in the geometrodynamical model of hadrons. The asymptotic behaviour and the gross features are correctly reproduced, but in fine details there are deviations from the experimental data. (Atomindex citation 13:657997)
