Triviality and the Standard Model

  title={Triviality and the Standard Model},
  author={Elizabeth H. Simmons and Bogdan A. Dobrescu},
The triviality of the scalar sector of the standard one-doublet Higgs model implies that this model is only an effective low-energy theory valid below some cutoff scale Λ. We show that the experimental constraint on the amount of custodial symmetry violation implies that the scale Λ must be greater than of order 7.5 TeV. The underlying high-energy theory must also include flavor dynamics at a scale of order Λ or greater in order to give rise to the different Yukawa couplings of the Higgs to… CONTINUE READING
