abstract = {Using data samples collected by the Belle and Belle II
experiments at the $Υ(4S)$ resonance with integrated
luminosities of 571 fb$^{-1}$ and 365 fb$^{-1}$,
respectively, we measure the pseudoscalar $B$-meson mass
difference to be $m(B^0)-m(B^+) = (0.495\pm0.024\pm0.005)$
MeV/c$^2$. The results are based on a simultaneous fit to
the variable $\tilde{M}_{bc}$, which is related to the $B$
momentum, for $B^0$ and $B^+$ candidates; and to the energy
dependence of ${\cal R}=σ(e^+e^-\to B^0\bar{B}^0) /
σ(e^+e^-\to B^+B^-)$, which is measured using changes in
the average center-of-mass energy over the data taking
periods. The phase-space hypothesis ${\cal
R}=(p_{B^0}/p_{B^+})^3$, upon which previous measurements
rely, is strongly disfavored by our fit; the measured
mass-difference value for the phase-space hypothesis also
differs significantly from our measurement. We constrain
${\cal R}$ in a broader energy range than covered by the
direct measurement and extract the energy dependence of
${\cal R}$ in the range from the $B\bar{B}$ threshold up to
10.59 GeV. We interpret the results using a phenomenological
model and constrain the parameters of the $B\bar{B}$
potential in the isovector channel.},
