Compatibility of recent $\mathrm{\Xi }$-nuclear bound state signals

J-PARC E05 reported recently a hint of a ${\mathrm{\Xi }}^{-}-{}^{11}\mathrm{B}$ nuclear state in the ${}^{12}\mathrm{C}(K^{-},K^{+}){}_{\mathrm{\Xi }}^{12}\mathrm{B}\mathrm{e}$ spectrum, bound by $B_{{\mathrm{\Xi }}^{-}}=8.9\pm 1.4{}_{-3.1}^{+3.8}$ MeV. Using a density-dependent $\mathrm{\Xi }$-nuclear optical potential $V_{\mathrm{o}\mathrm{p}\mathrm{t}}^{\mathrm{\Xi }}(\rho )$ we explore to what extent a ${\mathrm{\Xi }}_{1s}^{-}$ assignment of this nuclear state is compatible with ${\mathrm{\Xi }}_{1s}^{-}$ and ${\mathrm{\Xi }}_{1p}^{-}$ nuclear-state interpretations of ${\mathrm{\Xi }}^{-}$ capture events in light emulsion-nuclei experiments. We find that the only acceptable ${\mathrm{\Xi }}_{1s}^{-}$ assignment at present, barring an abnormally strong repulsive ${\rho }^2$ component of $V_{\mathrm{o}\mathrm{p}\mathrm{t}}^{\mathrm{\Xi }}(\rho )$, is that for the ${\mathrm{\Xi }}^{-}-{}^{11}\mathrm{B}$ signal. This finding supports reassigning ${\mathrm{\Xi }}^{-}$ capture events in ${}^{14}$N, originally assigned as ${\mathrm{\Xi }}_{1s}^{-}-{}^{14}\mathrm{N}$ nuclear states, to ${\mathrm{\Xi }}_{1p}^0-{}^{14}\mathrm{C}$ nuclear states. The depth of $V_{\mathrm{o}\mathrm{p}\mathrm{t}}^{\mathrm{\Xi }}(\rho )$ at nuclear-matter density ${\rho }_0=0.17$ fm${}^{-3}$ is then $-V_{\mathrm{o}\mathrm{p}\mathrm{t}}^{\mathrm{\Xi }}({\rho }_0)\sim 21$ MeV.
