Contribution

It introduces six new fields to achieve gauge coupling unification and addresses multiple fundamental cosmological and particle physics phenomena in a unified framework.

Findings

Achieves gauge coupling unification with six new fields

Explains dark matter, neutrino masses, and baryon asymmetry

Ensures vacuum stability and correct dark matter abundance

Abstract

We suggest a minimal extension of the standard model, which can explain current experimental data of the dark matter, small neutrino masses and baryon asymmetry of the universe, inflation, and dark energy, and achieve gauge coupling unification. The gauge coupling unification can explain the charge quantization, and be realized by introducing six new fields. We investigate the vacuum stability, coupling perturbativity, and correct dark matter abundance in this model by use of current experimental data.
