Light inflaton Hunter's Guide

Bezrukov, F., Gorbunov, D.

Understand

We study the phenomenology of a realistic version of the chaotic inflationary model, which can be fully and directly explored in particle physics experiments.

  • The inflaton mixes with the Standard Model Higgs boson via the scalar potential, and no additional scales above the electroweak scale are present in the model.
  • The inflaton-to-Higgs coupling is responsible for both reheating in the Early Universe and the inflaton production in particle collisions.
  • We find the allowed range of the light inflaton mass, 270 MeV<~m_chi<~1.8 GeV, and discuss the ways to find the inflaton.
