SU(5) Grand Unified Model and Dark Matter

TL;DR

This paper proposes a new SU(5) grand unified model with mirror dark matter, where all masses arise from interactions, allowing matter transformation at high energies and only gravitational interaction at low energies.

Contribution

It introduces a Higgs-less SU(5) x mirror SU(5) model with mass generation through interactions and dynamic matter transformation between visible and dark sectors.

Findings

Dark matter can transform into visible matter at high energies.

All particle masses originate from interactions, not Higgs fields.

Dark matter interacts only gravitationally at low energies.

Abstract

A dark matter model which is called w-matter or mirror dark matter is concretely constructed based on (f-SU(5))X(w-SU(5)) symmetry. There is no Higgs field and all masses originate from interactions in the present model. W-matter is dark matter relatively to f-matter and vice versa. In high-energy processes or when temperature is very high, visible matter and dark matter can transform from one into another. In such process energy seems to be non-conservational, because dark matter cannot be detected. In low-energy processes or when temperature is low, there is only gravitation interaction of dark matter for visible matter.
