Semileptonic *DELTA*S=1 decays of baryons with boosted bags

Recoil effects for strangeness-changing semileptonic decays of baryons by means of boosted quark mode solutions of the MIT bag model is calculated. Both the quark and the psevdoscalar part of the axial current is considered. It is shown that the induced scalar form factor f*sb3* and the ''weak electric'' form factor g*sb2* are proportional to the mass difference of the final and initial baryon. Moreover, it is shown that the quark wave function mismatch, which decreases the conventional vector form factor f*sb1*, can be compensated by recoil effects. Thus a better agreement with experiment seems to be achieved. (Auth.)
