  "abstract": "Motivated by the newly observed narrow structures $\\Omega_b(6316)^-$, $\\Omega_b(6330)^-$, $\\Omega_b(6340)^-$, and $\\Omega_b(6350)^-$ in the $\\Xi_b^0 K^-$ mass spectrum, we investigate the strong decays of the low-lying $\\Omega_b$ states within the $^3P_0$ model systematically. According to their masses and decay widths, the observed $\\Omega_b(6316)^-$, $\\Omega_b(6330)^-$, $\\Omega_b(6340)^-$, and $\\Omega_b(6350)^-$ can be reasonably assigned as the $\\lambda-$mode $\\Omega_b(1P)$ states with $J^P=1/2^-$, $J^P=3/2^-$, $J^P=3/2^-$, and $J^P=5/2^-$. Meanwhile, the remaining $J^P=1/2^-$ $P-$wave state should have a rather broad width, which can hardly be observed by experiments. For the $\\Omega_b(2S)$ and $\\Omega_b(1D)$ states, our predictions show that these states have relatively narrow total widths and mainly decay into the $\\Xi_b \\bar K$, $\\Xi_b^\\prime \\bar K$ and $\\Xi_b^{\\prime*} \\bar K$ final states. These abundant theoretical predictions may be valuable for searching more excited $\\Omega_b$ states in future experiments.",
