New Physics in $s\to u{\ell }^{-}\bar{\nu }$: Interplay between semileptonic kaon and hyperon decays

Martín González-Alonso, Jorge Martin Camalich

We review a novel model-independent approach to the analysis of new-physics effects in the $s\to u{\ell }^{-}\bar{\nu }$ transitions. We apply it to (semi)leptonic kaon decays and study thei…
