# Relaxation of Higgs mass and cosmological constant with four-form fluxes and reheating

## TL;DR

This paper explores how four-form fluxes in the Standard Model coupled to gravity can dynamically relax the Higgs mass and cosmological constant, while also addressing reheating after relaxation.

## Contribution

It introduces a non-minimal four-form coupling to gravity and a scalar inflaton field, providing a novel mechanism for Higgs mass relaxation and successful reheating.

## Key findings

- Higgs mass can be dynamically relaxed to the observed value.
- Transition probability to AdS space is extremely suppressed.
- A new scalar field can successfully reheat the universe after relaxation.

## Abstract

We consider the most general effective action for the four-form fluxes in the Standard Model coupled to gravity. The Higgs mass parameter can be relaxed to a correct value due to the four-form coupling to the Higgs field and it stops changing due to an extremely suppressed transition probability from the observed cosmological constant to AdS space. We first introduce a non-minimal four-form coupling to gravity and discuss the role of a new scalar field as the inflaton and the conditions for a successful reheating at the end of relaxation.
