Assigning the newly reported ${\Sigma }_b(6097)$ as a $P$-wave excited state and predicting its partners

Abstract

The newly observed ${\Sigma }_b(6097)$ provides us a good chance to further construct the high excited states of the bottom baryon family. In this work, we explain the ${\Sigma }_b(6097)$ to be a $1P$ state with $J^P=5/2^{-}$ or $3/2^{-}$ by giving the mass spectrum analysis and the strong decay calculation, and predict the existence of $1P$ and $2S$ partners of the ${\Sigma }_b(6097)$, where their masses and the corresponding decay behaviors are presented. Because of the success of describing the ${\Sigma }_b(6097)$ and the former observed ${\Xi }_b(6227)$ under the quasi-two-body treatment to the bottom baryons, we continue to predict the ${\Omega }_b$ partners of ${\Sigma }_b(6097)$ by the same method, which are the $1P$ and $2S$ states of the $bss$ baryon system. Identifying these predicted bottom baryons will be a research topic full of challenge and opportunity for future experiments especially the LHCb.
