# ${{\boldsymbol B}^{\pm}}$ MASS INSPIRE search

The fit uses ${\mathit m}_{{{\mathit B}^{+}}}$, (${\mathit m}_{{{\mathit B}^{0}}}–{\mathit m}_{{{\mathit B}^{+}}}$), and ${\mathit m}_{{{\mathit B}^{0}}}$ to determine ${\mathit m}_{{{\mathit B}^{+}}}$, ${\mathit m}_{{{\mathit B}^{0}}}$, and the mass difference.

1  Uses ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit K}^{+}}$ fully reconstructed decays.
2  Uses exclusively reconstructed final states containing a ${{\mathit J / \psi}}$ $\rightarrow$ ${{\mathit \mu}^{+}}{{\mathit \mu}^{-}}$ decays.
3  CSORNA 2000 uses fully reconstructed 526 ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{}^{(')}$ ${{\mathit K}^{+}}$ events and invariant masses without beam constraint.
4  ALBRECHT 1990J assumes 10580 for ${{\mathit \Upsilon}{(4S)}}$ mass. Supersedes ALBRECHT 1987C and ALBRECHT 1987D.
5  Found using fully reconstructed decays with ${{\mathit J / \psi}{(1S)}}$. ALBRECHT 1987D assume ${\mathit m}_{{{\mathit \Upsilon}{(4S)}}}$ = 10577 MeV.
