Towards models with a unified dynamical mechanism for elementary particle masses (1811.10326v1)

Published 26 Nov 2018 in hep-lat and hep-th

Abstract: Numerical evidence for a new dynamical mechanism of elementary particle mass generation has been found by lattice simulation in a simple, yet highly non-trivial SU(3) gauge model where a SU(2) doublet of strongly interacting fermions is coupled to a complex scalar field doublet via a Yukawa and a Wilson-like term. We point out that if, as a next step towards the construction of a realistic beyond-the-Standard-Model model, weak interactions are introduced, then also weak bosons get a mass by the very same non-perturbative mechanism. In this scenario fermion mass hierarchy can be naturally understood owing to the peculiar gauge coupling dependence of the non-perturbatively generated masses. Hence, if the phenomenological value of the mass of the top quark or the weak bosons has to be reproduced, the RGI scale of the theory must be much larger than $\Lambda_{QCD}$. This feature hints at the existence of new strong interactions and particles at a scale $\Lambda_T$ of a few TeV. In such a speculative framework the electroweak scale can be derived from the basic scale $\Lambda_T$ and the Higgs boson should arise as a bound state in the $WW+ZZ$ channel.
