Alternative $[SU(3){]}^4$ Model of Leptonic Color and Dark Matter

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.
