Probing non-standard charged-current interactions: from cold neutrons to the LHC

Abstract

It is well known that semileptonic decays of light hadrons and nuclei can be used not only to determine the CKM element V_ud with high accuracy, but also as probes of physics beyond the Standard Model. In this talk I review recent works that studied this within an Effective Field Theory framework, comparing the sensitivity of different low-energy and LHC observables. A clear complementarity between low- and high-energy searches it is found.
