| A measurement of the ratio of light-lepton inclusive semileptonic $B$ decay rates $R(X_{e/\mu})$ = $\mathcal{B}(B\to X e \nu)$ / $\mathcal{B}(B\to X \mu \nu)$ using $189\,\mathrm{fb}^{-1}$ of data at Belle~II

16 December 2022
In this work a measurement of the ratio of branching fractions of inclusive semileptonic $B$ meson decays, $R(X_{e/\mu})=\mathcal{B}(B\to X e \nu)/\mathcal{B}(B\to X \mu \nu)$ is reported as a probe of $e-\mu$ universality [...]
