Gravitational waves from the first order phase transition of the Higgs field at high energy scales

TL;DR

This paper investigates the potential for high-energy first order phase transitions of the Higgs field, induced by couplings with scalar fields in new physics models, and estimates the resulting gravitational wave signals.

Contribution

It explores the possibility of Higgs field phase transitions at high energy scales and estimates the associated gravitational wave production, linking particle physics with observable cosmological signals.

Findings

High energy scale phase transitions of the Higgs can produce detectable gravitational waves.

Couplings with scalar fields influence the nature and strength of the phase transition.

Potential observational signatures in gravitational wave detectors are discussed.

Abstract

In a wide class of new physics models, there exist scalar fields that obtain vacuum expectation values of high energy scales. We study the possibility that the standard model Higgs field has experienced first order phase transition at the high energy scale due to the couplings with these scalar fields. We estimate the amount of gravitational waves produced by the phase transition, and discuss observational consequences.
