Rare decays, being dominated by short distance contributions within the standard model (SM), open a window for new physics (NP) searches at low energies. The
branching ratios are expected to be measured with
accuracies by NA62/CERN and KOTO/JPARC. The theoretical uncertainties of branching ratios within the SM are well under control. In the B sector, it is tentative to explain the B-meson anomalies
and/or
by effects of physics beyond the SM. Although NP seems to be present in the third fermion generation it might also manifest in the flavor changing neutral current transition
. Together with the anticipated good experimental sensitivities and accurate theoretical predictions for
, this motivates studies of correlated effects of NP in rare
and
decays. Here we consider the loop induced effects in
in two leptoquark models designed to address lepton-flavor universality violation in the
anomalies.
