QUARK-MODEL CALCULATION OF THE WEAK ELECTRIC COUPLING IN SEMI-LEPTONIC BARYON DECAY
Journal or Book Title
PHYSICAL REVIEW D
The weak electric form factor g2 is calculated in the nonrelativistic quark model (NRQM) and the MIT bag model for weak ΔS=1 semileptonic transitions. The bag-model result is g2/g1=0.30 with the NRQM result roughly twice this. Other weak transition form factors are tabulated, including expected SU(3)-breaking effects.
