In this work, we adopt the \(^3P_0\) model to investigate the strong decays of the low-lying doubly bottom baryons in the \(j-j\) coupling scheme systematically. In this scheme, we construct the formulism of \(^3P_0\) model under the spectator assumption, and then the heavy diquark symmetry is preserved automatically. Our results show that some of the \(\lambda\)-mode \(\Xi_{bb}(1P)\) and \(\Omega_{bb}(1P)\) states are narrow, which have good potentials to be observed by future experiments. For the low-lying \(\rho\)-mode and \(\rho\)-\(\lambda\) hybrid states, the Okubo-Zweig-Iizuka-allowed strong decays are highly suppressed and they should be extremely narrow. Future experiments can test our phenomenological predictions at the quark level.
