Phenomenology of an extended IDM with loop-generated fermion mass hierarchies
Result description
We perform a comprehensive analysis of the most distinctive and important phenomenological implications of the recently proposed mechanism of sequential loop generation of strong hierarchies in the Standard Model (SM) fermion mass spectra. This mechanism is consistently realized at the level of renormalizable interactions in an extended variant of the Inert Higgs Doublet model, possessing the additional Z(2)((1)) x Z(2)((2)) discrete and U-1X gauge family symmetries, while the matter sectors of the SM are extended by means of SU2L-singlet scalars, heavy vector-like leptons and quarks, as well as right-handed neutrinos. We thoroughly analyze the most stringent constraints on the model parameter space, coming from the Z' collider searches, related to the anomaly in lepton universality, and the muon anomalous magnetic moment, as well as provide benchmark points for further tests of the model and discuss possible 'standard candle' signatures relevant for future explorations.
