We study the semileptonic decays of the lowest-lying bc baryons to the lowest-lying cc baryons (Ξbc⁽′*⁾→ Ξcc⁽*⁾ and Ωbc⁽′*⁾→ Ωcc⁽*⁾), in the limit mb, mc ≫ ΛQCD and close to the zero recoil point. The separate heavy quark spin symmetries make it possible to describe all these decays using a single form factor. We also show how these constraints can be used to test the validity of different quark model calculations. bb to bc baryon decays are also discussed.
