1  AAIJ 2015AB reports [${\mathit m}_{{{\mathit B}_{{{J}}}^{0}}}–{\mathit m}_{{{\mathit B}^{+}}}$] $−$ ${\mathit m}_{{{\mathit \pi}^{-}}}$ = $444$ $\pm5$ $\pm7$ MeV which we adjust by the ${{\mathit \pi}^{-}}$ mass. The masses inside the square brackets were measured for each candidate event. The result assumes $\mathit P$ = ($-1){}^{J}$ and uses two relativistic Breit-Wigner functions in the fit for mass difference.
2  AAIJ 2015AB reports [${\mathit m}_{{{\mathit B}_{{{J}}}^{0}}}–{\mathit m}_{{{\mathit B}^{+}}}$] $−$ ${\mathit m}_{{{\mathit \pi}^{-}}}$ = $471$ $\pm22$ $\pm7$ MeV which we adjust by the ${{\mathit \pi}^{-}}$ mass. The masses inside the square brackets were measured for each candidate event. The result assumes $\mathit P$ = ($-1){}^{J}$ and uses three relativistic Breit-Wigner functions in the fit for mass difference.
