Gauge coupling unification in simplified grand gauge-Higgs unification
نویسندگان
چکیده
Grand gauge-Higgs unification of five dimensional SU(6) gauge theory on an orbifold $S^1/Z_2$ with localized kinetic terms is discussed. The Standard model (SM) fermions the boundaries and some massive bulk coupling to SM boundary are introduced. Taking power-law running contributions from fields into account, perturbative shown be realized at around $10^{14}$ GeV, which a few order smaller than scale four grand unified theories.

Towards A Realistic Grand Gauge-Higgs Unification
We investigate a 5D SU(6) grand gauge-Higgs unification model compactified on an orbifold S/Z2. Ordinary quarks and leptons, together with right-handed neutrinos, are just accommodated into a minimal set of representations of the gauge group, without introducing any exotic states in the same representations. The proton decay turns out to be forbidden at least at the tree level. We also find a c...
متن کاملMerging gauge coupling constants without Grand Unification
The merging of the running couplings constants of the weak, strong, and electromagnetic fields does not require the unification of these gauge fields at high energy. It can, in fact, be the property of a general fermionic system in which gauge bosons are not fundamental.

متن کاملMirage gauge coupling unification
We use compact D = 4, N = 1, Type IIB orientifolds as a testing ground for recent ideas about precocious gauge coupling unification and a low energy string scale. We find that certain such orientifolds have the interesting property that gauge couplings receive moduli-dependent corrections which mimic the effect of field theoretical logarithmic running. The effective cut-off scale for the logari...
متن کاملTowards A Realistic Grand Gauge-Higgs Unification Scenario
In this talk, we discuss an attempt to construct a realistic model of the grand gauge-Higgs unification. We investigate a 5D SU(6) grand gauge-Higgs unification model compactified on an orbifold S/Z2. Ordinary quarks and leptons, together with right-handed neutrinos, are just accommodated into a minimal set of representations of the gauge group, without introducing any exotic states in the same...
متن کاملHiggs-gauge unification without tadpoles
In orbifold gauge theories localized tadpoles can be radiatively generated at the fixed points where U(1) subgroups are conserved. If the Standard Model Higgs fields are identified with internal components of the bulk gauge fields (Higgs-gauge unification) in the presence of these tadpoles the Higgs mass becomes sensitive to the UV cutoff and electroweak symmetry breaking is spoiled. We find th...
