${{\mathit p}}{{\overline{\mathit p}}}$ at 1.96 TeV
1AAIJ 2015AB reports [${\mathit m}_{{{\mathit B}_{{{2}}}^{*0}}}{\mathit m}_{{{\mathit B}^{+}}}$] $−$ ${\mathit m}_{{{\mathit \pi}^{-}}}$ = $320.6$ $\pm0.4$ $\pm0.3$ MeV which we adjust by the ${{\mathit \pi}^{-}}$ mass. The masses inside the square brackets were measured for each candidate event.
2AALTONEN 2014I reports ${\mathit m}_{{{\mathit B}_{{{2}}}^{*}{(5747)}^{0}}}$ $−$ ${\mathit m}_{{{\mathit B}^{+}}}$ $−$ ${\mathit m}_{{{\mathit \pi}^{-}}}$ = $317.9$ $\pm1.2$ ${}^{+0.8}_{-0.9}$ MeV which we adjusted by the ${{\mathit \pi}^{-}}$ mass.
