Abstract
We study the semileptonic decays of the lowest-lying triply heavy baryons made from and quarks in the limit , and close to the zero-recoil point. The separate heavy-quark spin symmetries strongly constrain the matrix elements, leading to single form factors for , , and baryon decays. We also study the effects on these systems of using a -shaped confinement potential, as suggested by lattice QCD results for the interaction between three static quarks.
