To formulate a unified gauge framework based on a non-regular embedding of the exceptional Lie group E6 that accounts for both Standard Model physics and dark matter.
Constructed a symmetry breaking pathway decomposing the E6 exceptional group into a G(2) hidden strong sector and an SU(3)_A electroweak ancestor group.
Introduced a minimal scalar Higgs sector based on the 650-dimensional representation of E6.
Demonstrated that the (7, 1) scalar component of the 650 Higgs representation drives the symmetry breaking of G(2) into the color gauge group SU(3)_C.
Showed that the (1, 8) scalar component mediates the breaking of SU(3)_A into the electroweak subgroup SU(2)_L x U(1)_A.

Implication

Theoretical analysis demonstrates a non-regular E6 gauge symmetry breaking chain into G2 and SU(3), suggesting a unified origin for Standard Model forces and hidden dark matter.

Abstract

We developed a unified framework based on a special (non-regular) embedding of the exceptional group E₆ E 6 in which the main stage of symmetry breaking chain realizes E₆→ G(2) × SU(3)A E 6 → G ( 2 ) × S U ( 3 ) A . The exceptional factor G (2) plays the role of a hidden strong sector, while SU(3)A S U ( 3 ) A acts as an ancestor of the electroweak gauge group. A minimal scalar sector is organized around a 650 650 -based E₆ E 6 Higgs sector. Its G(2)× SU(3)A G ( 2 ) × S U ( 3 ) A components (7,1) ( 7 , 1 ) and (1,8) ( 1 , 8 ) implement the subsequent breaking steps G(2)→ SU(3)C G ( 2 ) → S U ( 3 ) C and SU(3)A→ SU(2)L× U(1)A S U ( 3 ) A → S U ( 2 ) L × U ( 1 )
