  Stimulated by the newly observed $\Lambda_b(6146)^0$ and $\Lambda_b(6152)^0$
resonances, we investigate the strong decays of the low-lying singly bottom
baryons within the quark pair creation model. Considering their masses and
decay modes, we tentatively assign these states as the $\lambda-$ mode
$\Lambda_b(2S)$, $\Lambda_b(1D)$, $\Sigma_b(2S)$, and $\Sigma_b(1P)$ states,
and then estimate their strong decay widths. Compared with the experimental
total widths and decay modes measured by the LHCb Collaboration, the
$\Lambda_b(6146)^0$ and $\Lambda_b(6152)^0$ can be reasonably clarified into
the $J^P=5/2^+$ and $J^P=3/2^+$ $\Lambda_b(1D)$ sates respectively, while other
canonical assignments are disfavored. Other low-lying bottom states are also
presented, where various narrow states may have good potential to be observed
in future LHCb experiments.
