NNMSM Type-II and III

TL;DR

This paper proposes two extensions of the standard model, NNMSM type-II and III, which achieve gauge coupling unification, dark matter abundance, neutrino masses, baryon asymmetry, inflation, and dark energy within current experimental constraints.

Contribution

Introduction of NNMSM type-II and III models that unify gauge couplings and address multiple cosmological and particle physics phenomena simultaneously.

Findings

Gauge coupling unification achieved with extra fields.

Regions exist with stable vacuum, perturbative couplings, and correct dark matter abundance.

Models compatible with current experimental data.

Abstract

We suggest two types of extension of the standard model, which are the so-called next to new minimal standard model (NNMSM) type-II and -III. They can achieve gauge coupling unification as well as suitable dark matter abundance, small neutrino masses, baryon asymmetry of the universe, inflation, and dark energy. The gauge coupling unification can be realized by introducing extra two or three new fields, and could explain the charge quantization. We also show that there are regions in which the vacuum stability, coupling perturbativity, and correct dark matter abundance can be realized with current experimental data at the same time.
