Semileptonic bc to cc and bb to bc Baryon Decays and Heavy Quark Spin Symmetry *

Abstract

We study the semileptonic decays of the lowest-lying bc baryons to the lowest-lying cc baryons (Ξ (′∗) bc →Ξ (∗) cc and Ω (′∗) bc →Ω (∗) cc ) , 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.
