abstract = {We report measurements of the ratios of branching fractions
$\mathcal{R}(D^{(*)+}) = \mathcal{B}(\overline{B}{}^0 \to
D^{(*)+} \,\tau^- \, \overline{\nu}_\tau) /
\mathcal{B}(\overline{B}{}^0 \to D^{(*)+} \, \ell^- \,
\overline{\nu}_\ell)$, where $\ell$ denotes either an
electron or a muon. These ratios test the universality of
the charged-current weak interaction. The results are based
on a $365\, \mathrm{fb}^{-1}$ data sample collected with the
Belle II detector at the SuperKEKB $e^+e^-$ collider, which
operates at a center-of-mass energy corresponding to the
$\Upsilon(4S)$ resonance, just above the threshold for
$B\overline{B}{}$ production. Signal candidates are
reconstructed by selecting events in which the companion $B$
meson from the $\Upsilon(4S) \to B\overline{B}{}$ decay is
identified in semileptonic modes. The $\tau$ lepton is
reconstructed via its leptonic decays. We obtain
$\mathcal{R}(D^+) = 0.418 \pm 0.074 ~({\mathrm{stat}}) \pm
0.051 ~({\mathrm{syst}})$ and $\mathcal{R}(D^{*+}) = 0.306
\pm 0.034 ~({\mathrm{stat}}) \pm 0.018 ~({\mathrm{syst}})$,
which are consistent with world average values. Accounting
for the correlation between them, these values differ from
the Standard Model expectation by a collective significance
of $1.7$ standard deviations.},
