Deciphering weak decays of triply heavy baryons by SU(3) analysis

Baryons with three heavy quarks are the last missing pieces of the lowest-lying baryon multiplets in the quark model after the discovery of doubly heavy baryons. In this work, we study nonleptonic weak decays of triply heavy baryons Omega(++)(ccc), Omega(-)(bbb), Omega(+)(ccb), and Omega(0)(cbb). Decay amplitudes for various processes have been parametrized in terms of the SU(3) irreducible nonperturbative amplitudes. A number of relations for the partial decay widths can be deduced from these results that can be examined in future. Some decay channels and cascade decay modes which likely to be used to reconstruct the triply heavy baryons have been also listed.

Automated summary

This study focuses on the nonleptonic weak decays of baryons with three heavy quarks and parametrizes the decay amplitudes in terms of SU(3) irreducible nonperturbative amplitudes. Several relations for the partial decay widths have been deduced from the results, which can be examined in the future. Additionally, potential decay channels and cascade decay modes for reconstructing triply heavy baryons have been listed.
