Inflation and dark matter after spontaneous Planck scale generation by hidden chiral symmetry breaking

TL;DR

This paper proposes a model where dynamical chiral symmetry breaking in a hidden sector generates the Planck scale and electroweak scale, with hidden pions as super heavy dark matter candidates produced during inflation.

Contribution

It introduces a novel framework linking hidden sector symmetry breaking to fundamental scales and dark matter production, including a Higgs-inflation-like mechanism.

Findings

Planck and electroweak scales generated dynamically

Hidden pions as super heavy dark matter candidates

Inflaton decay produces dark matter particles

Abstract

Dynamical chiral symmetry breaking in a QCD-like hidden sector is used to generate the Planck mass and the electroweak scale including the heavy right-handed neutrino mass. A real scalar field transmits the energy scale of the hidden sector to the visible sectors, playing besides a role of inflaton in the early Universe while realizing a Higgs-inflation-like model. Our dark matter candidates are hidden pions that raise due to dynamical chiral symmetry breaking. They are produced from the decay of inflaton. Unfortunately, it will be impossible to directly detect them, because they are super heavy ($10^{9\,\sim\,12}$ GeV), and moreover the interaction with the visible sector is extremely suppressed.
