“…In the lepton sector, the current measurements and SM predictions of the muon [43,44] and electron [45,46] anomalous magnetic moments and the limits on their EDMs [47][48][49] imply the following 95% probability bounds: [4] is that of identifying which operators, hence which observables, are sensitive to the strength of the Higgs interactions, rather than merely to the value of the New Physics scale M . In what follows we will discuss this point in greater detail and, starting from the analysis of refs.…”

Abstract:We reconsider the effective Lagrangian that describes a light Higgs-like boson and better clarify a few issues which were not exhaustively addressed in the previous literature. In particular we highlight the strategy to determine whether the dynamics responsible for the electroweak symmetry breaking is weakly or strongly interacting. We also discuss how the effective Lagrangian can be implemented into automatic tools for the calculation of Higgs decay rates and production cross sections.

Permanent electric dipole moments (EDMs) violate parity and timereversal symmetry. Within the Standard Model (SM) they are many orders of magnitude below present experimental sensitivity. Many extensions of the SM predict much larger EDMs, which are therefore an excellent probe for the existence of "new physics". Until recently it was believed that only electrically neutral systems could be used for sensitive searches of EDMs. With the introduction of a novel experimental method, high precision for charged systems will be within reach as well. The features of this method and its possibilities are discussed.Keywords Permanent electric dipole moment · Standard model test · New physics search MotivationThe symmetry properties of fundamental processes and particles are a strong guide to understand the underlying interactions. The QED Lagrangian in the current Standard Model (SM) predicts that all electromagnetic observables are even under the discrete symmetries C (charge conjugation), P (parity) and T (time reversal) individually and thus under each combinations of them. Strong interaction observables, described by QCD, are also predicted to be even under C, P and T , with the exception of those proportional toθ which are P and T -odd [1]. The weak interaction violates both P and C because of the handedness of the coupling of the W and Z-bosons. Many observables are even under their combination CP. Nevertheless, the weak interaction also predicts CP-odd ones. These are all proportional to the Jarlskog invariant, J ∝ sin 2 θ 12 sin θ 23 sin θ 13 sin δ ∼ 3 × 10 −5 [2]. Here θ 12 , θ 23 and θ 13 are the quark flavor mixing angles and δ the CP-violating complex phase associated
