"Non-standard charged current interactions: from beta decays to the LHC"

The study of beta decays has historically played a central role in establishing what we now call the Standard Model of electroweak interactions. Nowadays, precision studies  of semi-leptonic decays involving light quark flavors (u,d,s)  can reveal signatures of non-standard interactions 

arising from broad classes of Standard Model extensions. 

 

In this talk I describe the status and prospects of precision low-energy tests involving 

beta decays  and the interplay of these low-energy probes with  searches at the Large Hadron Collider. 

 

I will first focus on the scenario in which  the new physics originates in the multi-TeV scale, in which  a direct comparison of low-energy and LHC searches can be performed in an effective theory framework. 

 

I will then discuss some examples in which the mediators of the new interactions  become accessible at the LHC.
