Abstract

Weak current-induced baryonic form factors at zero recoil are evaluated in the rest frame of the heavy parent baryon using the nonrelativistic quark model. Contrary to previous similar work in the literature, our quark model results do satisfy the constraints imposed by heavy quark symmetry for heavy-heavy baryon transitions. Assuming a dipole q² behavior, we have applied the quark model form factors to nonleptonic, semileptonic and weak radiative decays of the heavy baryons.
