Decay properties of $P$-wave heavy baryons accompanied by vector mesons within light-cone sum rules

We use the method of light-cone sum rules to study decay properties of $P$-wave bottom baryons belonging to the $SU(3)$ flavor ${\mathbf{6}}_F$ representation. In Ref.~\cite{Cui:2019dzj} we have studied their mass spectrum and pionic decays, and found that the ${\mathrm{\Sigma }}_b(6097)$ and ${\mathrm{\Xi }}_b(6227)$ can be well interpreted as $P$-wave bottom baryons of $J^P=3\mathrm{/}{2}^{-}$. In this paper we further study their decays into ground-state bottom baryons and vector mesons. We propose to search for a new state ${\mathrm{\Xi }}_b({5\mathrm{/}2}^{-})$, that is the $J^P = 5/2^-$partnerstateofthe$\Xi_{b}(6227)$,inthe$\Xi_b({5/2}^-) \to \Xi_b^{}\rho \to \Xi_b^{}\pi\pi$decayprocess\mathrm{.}Itsmassis$12 \pm 5$~MeV larger than that of the ${\mathrm{\Xi }}_b(6227)$.
