Strong decays of the low-lying doubly bottom baryons

In this work, we adopt the $^{3}{P}_{0}$ model to investigate strong decays of low-lying doubly bottom baryons in $j\ensuremath{-}j$ coupling scheme systematically. scheme, construct formulism under spectator assumption, and then heavy diquark symmetry is preserved automatically. Our results show that some $\ensuremath{\lambda}$-mode ${\mathrm{\ensuremath{\Xi}}}_{bb}(1P)$ ${\mathrm{\ensuremath{\Omega}}}_{bb}(1P)$ states are narrow, which have good potentials be observed by future experiments. For $\ensuremath{\rho}$-mode $\ensuremath{\rho}\text{\ensuremath{-}}\ensuremath{\lambda}$ hybrid states, Okubo-Zweig-Iizuka-allowed highly suppressed they should extremely narrow. Future experiments can test our phenomenological predictions at quark level.
