Abstract
The first-order SU(3) symmetry breaking in semi-leptonic decays is studied by use of the techniques of equal time commutators. The correction for the baryon axial-vector decay constants is related to that for the strong derivative coupling constants of pseudoscalar meson-baryon interaction. It is further found that the Kl2 and πl2 decay constants remain unrenormalized so that fK=fπ.
