The Standard model as a low-energy effective theory: what is triggering the Higgs mechanism?

Understand

The discovery of the Higgs by ATLAS and CMS at the LHC not only provided the last missing building block of the electroweak Standard Model, the mass of the Higgs has been found to have a very peculiar value about 126 GeV, which is such that vacuum stability is extending up to the Planck scale.

• This may have much deeper drawback than anticipated so far.
• The impact on the running of the SM gauge, Yukawa and Higgs couplings up to the Planck scale has been discussed in several articles recently.
• Here we consider the impact on the running masses and we discuss the role of quadratic divergences within the Standard Model.
