Classically Scale Invariant Inflation, Supermassive WIMPs, and Adimensional Gravity

Understand

We introduce a minimal and yet comprehensive framework with $CP$- and classical scale-symmetries, in order to simultaneously address the hierarchy problem, neutrino masses, dark matter, and inflation.

• One complex gauge singlet scalar and three flavors of the right-handed Majorana neutrinos are added to the standard model content, facilitating the see-saw mechanism, among others.
• An adimensional theory of gravity (Agravity) is employed, allowing for the trans-Planckian field excursions.
• The weak and Planck scales are induced by the Higgs portal and the scalar non-minimal couplings, respectively, once a Coleman-Weinberg dynamically-generated vacuum expectation value for the singlet scalar is obtained.
