Abstract

Baryons with a heavy c-quark or a heavy b-quark and also two c-quarks have been discovered. These states are expected in QCD and therefore provide a test for the theory. There should be double beauty baryons, and also an intriguing possibility that baryons Bbc with a c-quark, a b-quark. These states are yet to be discovered. The main decay modes of Bbc are expected to be weak processes from theoretical understanding of their mass spectrum. These decay modes can provide crucial information about these heavy baryons Bbc. We analyze two body hadronic weak decays for Bbc using SU(3) flavor symmetry. Any one of the c and b decays will induce Bbc to decay. We find that the Cabibbo allowed decays Bbc→Bb+M due to c→sud can be crucial for exploration. The LHC may have the sensitivity to discover such decays. Other Bbc decays due to b→cq′q are subleading. Several relations among branching ratios are obtained which can be used to test SU(3) flavor symmetry. [ABSTRACT FROM AUTHOR]
