“…In previous studies of the 331 model [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][43][44][45][46][47], two Higgs doublets are assumed at the EW scale, which come from the 6 H 1 (chosen to be ρ = 1 without loss of generality) and the 15 H , respectively.…”

We study a toy SU(6) model with the symmetry breaking pattern of the extended 331 symmetry of SU(3) c ⊗ SU(3) W ⊗ U(1) X . A "fermion-Higgs mismatching" symmetry breaking pattern is proposed for more realistic model building. Within such symmetry breaking pattern, only one Higgs doublet develops vacuum expectation value for the spontaneous electroweak symmetry breaking, and gives tree-level top quark mass. A natural VEV splittings in the 331 breaking Higgs fields gives treelevel masses to both bottom quark and tau lepton. The 125 GeV SM-like Higgs boson discovered at the LHC can have Yukawa couplings to bottom quark and tau lepton as in the SM prediction, and this sets the 331 symmetry breaking scale at ∼ O(10) TeV.

“…The emergent PQ symmetry, together with both the gauge and the global symmetries, can usually constrain the mass dimensions of the PQ-breaking operators and lead to a high-quality axion [22,[25][26][27][28][29]. Two recent examples include the axion from the [30] and the SUSY GUT [31].…”

We extend the unitary groups beyond the ${\rm SU}(5)$ and ${\rm SU}(6)$ to look for possible grand unified theories that give rise to three-generational Standard Model fermions without the simple repetition. By demanding asymptotic free theories at short distances, we find gauge groups of ${\rm SU}(7)$, ${\rm SU}(8)$ and ${\rm SU}(9)$ together with their anomaly-free irreducible representations are such candidates. Two additional gauge groups of ${\rm SU}(10)$ and ${\rm SU}(11)$ can also achieve the generational structure without asymptotic freedom. We also find these models can solve the Peccei-Quinn (PQ) quality problem which is intrinsic in the axion models, with the leading PQ-breaking operators determined from the symmetry requirement.

“…For instance, in "accidental" axion models the PQ-charged fields are also charged under some locally conserved symmetries, so that all gauge-invariant PQ-charged operators are necessarily higher-dimensional, and the PQ breaking ∼ (f a /M p ) n is suppressed by multiple powers of the Planck mass M p . The local symmetry may be discrete [163][164][165][166] or continuous [167][168][169][170][171][172]. In composite axion models [173][174][175][176][177][178] the axion is a baryon-like particle, composed of quarks charged under a strongly coupled non-Abelian gauge group.…”
