The Higgs field as an inflaton

TL;DR

This paper reviews how the Standard Model Higgs field, when non-minimally coupled to gravity, can drive early Universe inflation, matching CMB observations and impacting Higgs mass predictions, while discussing quantization issues.

Contribution

It provides a comprehensive review of Higgs inflation models, their predictions, and related quantization problems, highlighting their consistency with current cosmological data.

Findings

Higgs inflation predicts CMB parameters in agreement with observations

The model links Higgs boson mass to inflationary dynamics

Quantization issues pose challenges for the model

Abstract

The Higgs field of the pure Standard Model can lead to the inflationary expansion of the early Universe if it is non-minimally coupled to gravity. The model predicts Cosmic Microwave Background (CMB) parameters in perfect agreement with the current observations and has implications for the Higgs boson mass. We review the model, its predictions, problems arising with its quantization and some closely related models.
