abstract = {We present a search for the rare flavor-changing
neutral-current decay $B^0 \to K^{\ast 0} \tau^+ \tau^-$
with data collected by the Belle II experiment at the
SuperKEKB electron-positron collider. The analysis uses a
365 fb$^{-1}$ data sample recorded at the center-of-mass
energy of the $\Upsilon(4S)$ resonance. One of the $B$
mesons produced in the $\Upsilon(4S)\to B^0 \bar{B}^0$
process is fully reconstructed in a hadronic decay mode,
while its companion $B$ meson is required to decay into a
$K^{\ast 0}$ and two $\tau$ leptons of opposite charge. The
$\tau$ leptons are reconstructed in final states with a
single electron, muon, charged pion or charged $\rho$ meson,
and additional neutrinos. We set an upper limit on the
branching ratio of $BR(B^0 \to K^{\ast 0} \tau^+ \tau^-) <
1.8 \times 10^{-3}$ at the 90\% confidence level, which is
the most stringent constraint reported to date.},
