Abstract

We investigate PP-wave bottom baryons of the SU(3)SU(3) flavor 6F\mathbf{6}_F, and systematically study their DD-wave decays into ground-state bottom baryons and pseudoscalar mesons. Together with [PRD91, 054034 (2015); PRD92, 114007 (2015); PRD95, 094008 (2017); EPJC80, 80 (2020)], a rather complete study is performed on both mass spectra and decay properties of PP-wave bottom baryons, using the method of QCD sum rules and light-cone sum rules within the framework of heavy quark effective theory. Among all the possibilities, we find four Σb\Sigma_b, four Ξb\Xi^\prime_b, and six Ωb\Omega_b baryons, with limited widths and so capable of being observed. Their masses, mass splittings within the same multiplets, and decay properties are extracted (summarized in Table V) for future experimental searchings.
