Scalar leptoquarks in flavour physics
We reinvestigate contributions of scalar leptoquarks in $R_{D^{(\ast)}}$ anomalies and use constraints from the branching fractions of $B\to K^{(\ast)} \nu \bar \nu$ decays. Then, we update the constraints on parameter space and find which scalar leptoquarks remain viable and consistent with low- and high-energy flavour physics constraints. We comment on the implications of such selection.
