$21.2$ ${}^{+2.0}_{-1.9}$ ${}^{+0.4}_{-0.3}$ 1
 2007 K
CDF ${{\mathit p}}{{\overline{\mathit p}}}$ at 1.96 TeV
 1 Observed four ${{\mathit \Lambda}_{{b}}^{0}}{{\mathit \pi}^{\pm}}$ resonances in the fully reconstructed decay mode ${{\mathit \Lambda}_{{b}}^{0}}$ $\rightarrow$ ${{\mathit \Lambda}_{{c}}^{+}}{{\mathit \pi}^{-}}$ , where ${{\mathit \Lambda}_{{c}}^{+}}$ $\rightarrow$ ${{\mathit p}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$ . Assumes ${\mathit m}_{{{\mathit \Sigma}_{{b}}^{*+}}}–{\mathit m}_{{{\mathit \Sigma}_{{b}}^{+}}}$ = ${\mathit m}_{{{\mathit \Sigma}_{{b}}^{*-}}}–{\mathit m}_{{{\mathit \Sigma}_{{b}}^{-}}}$
