Gauge Hierarchy in SU(3)c × SU(3)L × SU(3)R and Low Energy Implications
نویسنده
چکیده
We explore the gauge hierarchy problem within the framework of supersymmetric SU(3)c × SU(3)L × SU(3)R with a minimal set of higgs supermultiplets. Imposition of a suitable discrete (alternatively R) symmetry ‘prevents’ the electroweak higgs doublets from becoming superheavy through renormalizable couplings. A full resolution of the problem requires consideration of the non-renormalizable couplings which play an essential role. Other key differences from the minimal supersymmetric SU(5) model include the fact that the proton is stable and that an effective 5 + 5̄ supermultiplet appears around the TeV mass scale.

Quark-Lepton Quartification
We propose that quarks and leptons are interchangeable entities in the high-energy limit. This naturally results in the extension of [SU(3)] trinification to [SU(3)] quartification. In addition to the unbroken color SU(3)q of quarks, there is now also a color SU(3)l of leptons which reduces to an unbroken SU(2)l. We discuss the natural occurrence of SU(2)l doublets at the TeV energy scale, whic...
متن کاملExotic Fermions and Bosons in the Quartification Model
Exotic fermions of half-integral charges at the TeV energy scale are predicted by the quartification model of Babu, Ma, and Willenbrock. We add to these one copy of their scalar analogs and discuss the ensuing phenomenological implications, i.e. radiative contributions to lepton masses and flavor-changing leptonic decays. In the recently proposed [1] model of SU(3) quartification, the low-energ...
متن کاملPossible Gauge Theoretic Origin for Quark-Lepton Complementarity
Similarity between the weak interaction properties of quarks and leptons has led to suggestions that the origin of lepton mixing angles may be related to those of quarks. In this paper, we present a gauge model based on SU(2)L×SU(2)R×SU(4)c group that leads to a new form for the quark lepton complementarity which predicts the solar neutrino mixing angle in terms of the Cabibbo angle for the cas...
متن کاملParameter Space Investigations of Free Fermionic Heterotic Models
I survey the parameter space of NAHE-based free fermionic heterotic string models. First, I discuss flat directions of the low energy effective field theories and show that D-flat directions need not be isomorphic to gauge invariant superpotential terms. Next, I review recent studies of three generation SU(3)C × SU(2)L × U(1)Y , SU(3)C ×SU(2)L ×SU(2)R ×U(1)B−L, SU(4)C × SU(2)L ×U(1)Y ′ , and fl...
متن کاملunification at TeV and cancellation of local gauge anomalies with split multiplets
We consider the 5D gauge unification of SU(2)L×U(1)Y into SU(3)W at a TeV scale. Compactification of the extra dimension on an orbifold S1/(Z2×Z ′ 2 ) allows fixed points where SU(2)L×U(1)Y representations can be assigned. We explain the long proton lifetime and the top-bottom mass hierarchy geometrically. We also show that local gauge anomalies on the orbifold can be exactly cancelled by a 5D ...
