Abstract
We study the semileptonic decays of the lowest-lying bc baryons to the lowest-lying
cc baryons (Xi_{bc}^{(\prime*)}--> Xi_{cc}^{(*)} and Omega_{bc}^{(\prime*)}--> Omega_{cc}^{(*)}),
in the limit m_b, m_c >> Lambda_{QCD} 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 recover results derived previously by White and Savage in a
manner which we think is more straightforward and parallels the method applied later
to study Bc semileptonic decays. We further discuss the resemblance between the bc
baryon decays and those of Bc mesons to eta_c and J/\psi mesons and comment on the
relation between the slopes of the single functions describing each set of decays.
Our results can straightforwardly be applied to the decays of bb baryons to bc baryons.
