A global Effective-Field-Theory analysis of $d(s)\to u\ell\nu$ transitions will be presented. The interplay of the various processes (kaon, pion, nuclear and baryon decays) will be discussed, along with the results of a combined fit.
The framework contains the usual SM analysis as a specific case, and it allows to understand the implications of any given SM test, such as the the well-known $V_{ud}−V_{us}$ diagram.
Finally, I will discuss the synergy with searches at high-energy colliders, such as the LHC.
