1  Uses exclusively reconstructed final states containing a ${{\mathit J / \psi}}$ $\rightarrow$ ${{\mathit \mu}^{+}}{{\mathit \mu}^{-}}$ decay.
2  Uses the ${{\mathit B}}$-momentum distributions in the ${{\mathit e}^{+}}{{\mathit e}^{-}}$ rest frame.
3  BEBEK 1987 actually measure the difference between half of $\mathit E_{{\mathrm {cm}}}$ and the ${{\mathit B}^{\pm}}$ or ${{\mathit B}^{0}}$ mass, so the ${\mathit m}_{{{\mathit B}^{0}}}–{\mathit m}_{{{\mathit B}^{\pm}}}$ is more accurate. Assume ${\mathit m}_{{{\mathit \Upsilon}{(4S)}}}$ = 10580 MeV.
