Footprints of leptoquarks: from $R_{K^{(\ast )}}$ to $K\to \pi \nu \bar{\nu }$

S. Fajfer, N. Košnik, L. Vale Silva

Rare $K\to \pi \nu \bar{\nu }$ decays, being dominated by short distance contributions within the Standard Model (SM), open a window for New Physics (NP) searches at low energies. The $ K \…
