Graviweak Unification in the Visible and Invisible Universe and Inflation from the Higgs Field False Vacuum

TL;DR

This paper proposes a unification model combining gravity and weak interactions within a $Spin(4,4)$ symmetry, and explores inflation driven by the Higgs false vacuum, leading to the emergence of Standard Model vacua in visible and invisible sectors.

Contribution

It introduces a self-consistent $Spin(4,4)$-invariant unification model and links the Higgs false vacuum to inflation and the formation of SM vacua in visible and mirror worlds.

Findings

Inflation initiated from the Higgs false vacuum at $10^{18}$ GeV.

Emergence of SM vacua with Higgs VEVs in visible and mirror sectors.

A unified framework connecting gravity, weak interactions, and cosmological inflation.

Abstract

In the present paper we develop the self-consistent $Spin(4,4)$-invariant model of the unification of gravity with weak $SU(2)$ interactions in the assumption of the existence of visible and invisible sectors of the Universe. It was shown that the consequences of the multiple point principle predicting two degenerate vacua in the Standard Model (SM) suggest a theory of Inflation, in which the inflaton field $\sigma$ starts trapped in a cold coherent state in the "false vacuum" of the Universe at the value of the Higgs field's VEV $v\sim 10^{18}$ GeV (in the visible world). Then the inflations of the two Higgs doublet fields, visible $\phi$ and mirror $\phi'$, lead to the emergence of the SM vacua at the Electroweak scales with the Higgs boson VEVs $v_1\approx 246$ GeV and $v'_1=\zeta v_1$ (with $\zeta \sim 100$) in the visible and invisible worlds, respectively.
