Decoupling of Higgs boson from the inflationary stage of Universe evolution

TL;DR

This paper establishes a lower bound on the Higgs boson mass to prevent it from driving inflation in the early Universe, ensuring the Higgs remains decoupled from cosmological inflation and preserving large-scale structure.

Contribution

It derives a lower bound of 150 GeV on the Higgs mass to decouple it from inflation, linking particle physics with early Universe cosmology.

Findings

Higgs mass must be greater than 150 GeV to avoid inflationary effects.

Higgs cannot be responsible for inflation if its mass exceeds 150 GeV.

Decoupling of Higgs from inflation preserves large-scale structure integrity.

Abstract

The constraint on the mass of Higgs field in the Standard Model at the minimal interaction with the gravity is derived in the form of lower bound $m_H> 150$ GeV by the strict requirement of decoupling the Higgs boson from the inflation of early Universe: the inflation produced by the Higgs scalar could crucially destroy visible properties of large scale structure of Universe, while the large mass makes the Higgs particle not able to produce the inflation and shifts its cosmological role into the region of quantum gravity.
