The gravitational and electroweak interactions unified as a gauge theory of the De Sitter group

TL;DR

This paper proposes a geometric unification of gravity and electroweak interactions via a complexified de Sitter gauge theory, predicting new gravity-induced phenomena without a traditional Higgs sector.

Contribution

It introduces a novel gauge-theoretic framework unifying gravity and electroweak forces through the de Sitter group, eliminating the need for a Higgs field.

Findings

Standard electroweak spectrum recovered with correct masses

Predicted gravity-induced electroweak processes at high energy scales

Potential violations of the equivalence principle at 1 part in 10^{17}

Abstract

The complexified gauging of the de Sitter group gives a unified theory for the electroweak and gravitational interactions. The standard spectrum for the electroweak gauge bosons is recovered with the correct mass assignments, following a spontaneous breaking of the gauge symmetry imposed by the geometry. There is no conventional Higgs sector. New physics is predicted with gravity-induced electroweak processes (at the electroweak and at an intermediate scale of about $10^{10}Gev$) as well as with novel-type of effects (such as gravitational Aharonov-Bohm and violations of the Principle of equivalence to 1 part in $10^{17}$). The new theoretical perspectives emerging from this geometric unification are briefly discussed.
