 LHCB ${{\mathit p}}{{\mathit p}}$ at 7, 8 TeV
1  AAIJ 2015AB reports [${\mathit m}_{{{\mathit B}_{{J}}^{0}}}–{\mathit m}_{{{\mathit B}^{+}}}$] $−$ (${\mathit m}_{{{\mathit B}^{*+}}}–{\mathit m}_{{{\mathit B}^{+}}}$) $−$ ${\mathit m}_{{{\mathit \pi}^{-}}}$ = $552$ $\pm4$ $\pm5$ MeV which we adjust by the ${{\mathit \pi}^{-}}$ mass. The masses inside the square brackets were measured for each candidate event. The result assumes $\mathit P$ = $−(-1){}^{J}$, (${\mathit m}_{{{\mathit B}^{*+}}}–{\mathit m}_{{{\mathit B}^{+}}}$) = $45.01$ $\pm0.30$ $\pm0.23$ MeV, and uses three relativistic Breit-Wigner functions in the fit for mass difference.
