| 1 | Semileptonic bc to cc and bb to bc baryon decays and heavy quark spin symmetry显示文摘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 m b,m c Λ 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 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. | J.Nieves J.M.Flynn E.Hernández | 2010 | Chinese Physics C2010，34，9： | 0 |
