The reported result is ${\mathit m}_{{{\mathit B}_{{{s}}}^{0}}}{\mathit m}_{{{\mathit B}^{0}}}$ = $87.45$ $\pm0.44$ $\pm0.09$ MeV. We convert it to the mass difference with respect to the average of (${\mathit m}_{{{\mathit B}^{\pm}}}$ + ${\mathit m}_{{{\mathit B}^{0}}}$)/2. Uses the mode ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit \psi}{(2S)}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$.

The reported result is ${\mathit m}_{{{\mathit B}_{{{s}}}^{0}}}{\mathit m}_{{{\mathit B}^{+}}}$ = $87.52$ $\pm0.30$ $\pm0.12$ MeV. We convert it to the mass difference with respect to the average of (${\mathit m}_{{{\mathit B}^{\pm}}}$ + ${\mathit m}_{{{\mathit B}^{0}}}$)/2.

The reported result is ${\mathit m}_{{{\mathit B}^{0}_{s}}}$ $−$ ${\mathit m}_{{{\mathit B}^{0}}}$ = $86.38$ $\pm0.90$ $\pm0.06$ MeV. We convert it to the mass difference with respect to the average of (${\mathit m}_{{{\mathit B}^{\pm}}}$ + ${\mathit m}_{{{\mathit B}^{0}}}$)/2.
