${{\mathit B}^{0}}$ MASS

INSPIRE   PDGID:
S042M
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 ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit p}}{{\overline{\mathit p}}}$ decays.
2  Measured with ${{\mathit B}_{{d}}^{0}}$ $\rightarrow$ ${{\mathit J / \psi}}$ ( ${{\mathit \mu}^{+}}{{\mathit \mu}^{-}}$ ) ${{\mathit K}_S^0}$ ( ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ ) decays.
3  Uses ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit K}^{0}}$ fully reconstructed decays.
4  Uses exclusively reconstructed final states containing a ${{\mathit J / \psi}}$ $\rightarrow$ ${{\mathit \mu}^{+}}{{\mathit \mu}^{-}}$ decays.
5  CSORNA 2000 uses fully reconstructed 135 ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit J / \psi}}{}^{(')}$ ${{\mathit K}_S^0}$ events and invariant masses without beam constraint.
6  ALBRECHT 1990J assumes 10580 for ${{\mathit \Upsilon}{(4S)}}$ mass. Supersedes ALBRECHT 1987C and ALBRECHT 1987D.
7  Found using fully reconstructed decays with ${{\mathit J / \psi}}$. ALBRECHT 1987D assume ${\mathit m}_{{{\mathit \Upsilon}{(4S)}}}$ = 10577 MeV.
