In this talk I will discuss the New Physics (NP) implications of the precise measurements performed in muon and beta decays. Within an Effective Field Theory framework, we analyze which effective operators can be proved in these experiments and we show their complementarity with LHC searches. We will show that in flavor diagonal NP models, CKM unitarity is the only observable sensitive to NP, giving strong constraints on the NP effective scale (11 TeV). In more general flavor scenarios, scalar and tensor interactions appear, giving a richer phenomenology. I will revisite the current and future bounds on these interactions showing that in the next few years the LHC and (ultra) cold neutron experiments will give the strongest constraints on them.
