  Two bottom $\Sigma_b(6097)^\pm$ baryons were observed in the final states
$\Lambda_b^0\pi^-$ and $\Lambda_b^0\pi^+$ in $pp$ collision by LHCb
collaboration, whose masses and widths were measured. In a $^{3}P_{0}$ model,
the strong decay widths of two ground $S$-wave and seven excited $P$-wave
$\Sigma_b$ baryons have been systematically computed. Numerical results
indicate that the newly observed $\Sigma_b(6097)^\pm$ are very possibly
$\Sigma_{b2}^1({3\over 2}^-)$ with $J^P={3\over 2}^-$ or $\Sigma_{b2}^1({5\over
2}^-)$ with $J^P={5\over 2}^-$. The predicted decay widths of
$\Sigma_b(6097)^\pm$ are consistent with experimental measurement from LHCb. In
particular, it may be possible to distinguish these two assignments through
ratios $\Gamma({\Sigma_b(6097)^\pm\to
\Sigma_b^\pm\pi^0})/\Gamma({\Sigma_b(6097)^\pm\to \Sigma_b^{*\pm}\pi^0})$,
which can be measured by experiments in the future. In the meantime, our
results support the assignments that $\Sigma_b^\pm$ and $\Sigma_b^{*\pm}$ are
the ground $S$-wave $\Sigma_b$ baryons with $J^P={1\over 2}^+$ and $J^P={3\over
2}^+$, respectively.
