Abstract

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