The ${\mathrm{\ensuremath{\Xi}}}_{b}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ invariant mass spectrum is investigated with an event sample of proton-proton collisions at $\sqrt{s}=13\text{ }\text{ }\mathrm{TeV}$, collected by the CMS experiment at the LHC in 2016--2018 and corresponding to an integrated luminosity of $140\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$. The ground state ${\mathrm{\ensuremath{\Xi}}}_{b}^{\ensuremath{-}}$ …
