Weak-Scale Higgs Inflation

Understand

The present measurement of the standard model (SM) parameters suggests that the Higgs effective potential has a maximum at the intermediate scale, and the electroweak (EW) vacuum is not absolutely stable.

• The simplest possibility for absolute EW stability may be introducing a very large Higgs-Ricci scalar non-minimal coupling.
• In this extension of the SM, I study the cosmic inflation driven by the Higgs field.
• Since the resulting Hubble parameter happens to be around the weak scale, I call this scenario $weak\text{-}scale\text{ }Higgs\text{ }inflation$.
