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

INSPIRE   PDGID:

S041M

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.

Supersedes ALBRECHT 1987C and ALBRECHT 1987D. 6  Found using fully reconstructed decays with ${{\mathit J / \psi}{(1S)}}$. ALBRECHT 1987D assume ${\mathit m}_{{{\mathit \Upsilon}{(4S)}}}$ = 10577 MeV.
