New physics in $s\to d$ semileptonic transitions: rare hyperon vs. kaon decays

Li-Sheng Geng, Jorge Martin Camalich, Rui-Xiang Shi

We investigate the potential of rare hyperon decays to probe the short distance structure in the $s\to d\nu \bar{\nu }$ and $s\to d{\ell }^{+}{\ell }^{-}$ transitions. Hyperon decays into neutrinos…
