The phase diagram of the $U (2) \times U (2)$ Sigma Model and its Implications for Chiral Hierarchies

D. Espriu, V. Koulovassilopoulos, A. Travesset

Motivated by the issue of whether it is possible to construct phenomenologically viable models where the electroweak symmetry breaking is triggered by new physics at a scale $Λ\gg…

When is a Higgs THE Higgs?

R. Sekhar Chivukula, Vassillis Koulovassilopoulos

The one-Higgs-doublet standard model is necessarily incomplete because of the triviality of the scalar symmetry-breaking sector. If the Higgs mass is approximately 600 GeV or highe…
