TL;DR

This paper introduces an alternative $[SU(3)]^4$ model that unifies leptonic color and dark matter at high energies, featuring unique low-energy gauge groups and novel hemion particles that could be explored at future colliders.

Contribution

It proposes a new $[SU(3)]^4$ model with distinctive low-energy gauge structure and hemion doublets, providing a novel framework for leptonic color and dark matter.

Findings

Unification at $10^{14}$ GeV with specific low-energy subgroup.

Presence of hemion doublets with half-integer charges confined by $SU(2)_l$.

Potential detection of hemionia states at future $e^-e^+$ colliders.

Abstract

The alternative $[SU(3)]^4$ model of leptonic color and dark matter is discussed. It unifies at $M_U \sim 10^{14}$ GeV and has the low-energy subgroup $SU(3)_q \times SU(2)_l \times SU(2)_L \times SU(2)_R \times U(1)_X$ with $(u,h)_R$ instead of $(u,d)_R$ as doublets under $SU(2)_R$. It has the built-in global $U(1)$ dark symmetry which is generalized $B-L$. In analogy to $SU(3)_q$ quark triplets, it has $SU(2)_l$ hemion doublets which have half-integral charges and are confined by $SU(2)_l$ gauge bosons (stickons). In analogy to quarkonia, their vector bound states (hemionia) are uniquely suited for exploration at a future $e^-e^+$ collider.
