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  AALTONEN 2014I reports ${\mathit m}_{{{\mathit B}_{{J}}{(5970)}^{+}}}$ $−$ ${\mathit m}_{{{\mathit B}^{0}}}$ $−$ ${\mathit m}_{{{\mathit \pi}^{+}}}$ = $541$ $\pm5$ $\pm12$ MeV which we adjusted by the ${{\mathit \pi}^{+}}$ mass. 3  AAIJ 2015AB reports [${\mathit m}_{{{\mathit B}_{{J}}^{+}}}–{\mathit m}_{{{\mathit B}^{0}}}$] $−$ ${\mathit m}_{{{\mathit \pi}^{+}}}$ = $547$ $\pm5$ $\pm3$ 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.
