[SU(3)× SU(2)× U(1)] and Strong Unification
نویسنده
چکیده
A supersymmetric model with gauge symmetry G1 × G2, where Gi = SU(3)i × SU(2)i × U(1)i, is constructed within the framework of gauge mediated supersymmetry breaking. At the energy scale ∼ (10− 100) TeV where the gauge symmetry breaks down to the Standard Model (SM), G1 is strong and G2 is weak. The observed gauge coupling constant unification of the SM is attributed to that of G2. The messenger fields and Higgs fields just satisfy the condition that makes G2 a realization of strong unification. The SM gauginos are predicted to be generally heavier than the sleptons and squarks.

Quantum Weakdynamics as an SU(3)I Gauge Theory: Grand Unification of Strong and Electroweak Interactions
Quantum weakdynamics (QWD) as an SU(3)I gauge theory with the Θ vacuum term is considered to be the unification of the electroweak interaction as an SU(2)L × U(1)Y gauge theory. The grand unification of SU(3)I × SU(3)C beyond the standard model SU(3)C × SU(2)L × U(1)Y is established by the group SU(3)I . The grand unified interactions break down to weak and strong interactions at a new grand un...
متن کاملQuantum Restoration of the U(1)Y Symmetry in Dynamically Broken SUSY-GUT’s
We propose a supersymmetric hypercolor SU(3)H gauge theory interacting strongly at the grand unification scale, in which the hyperquark condensation breaks SU(5)GUT down to SU(3)C × SU(2)L without unbroken U(1)Y at the classical level. However, we show that the broken U(1)Y symmetry is restored by quantum mechanical effects and hence there remains the standard-model gauge symmetry at the electr...

There are certain difficulties in constructing a noncommutative quantum field theory (NCQFT) for strong and electroweak interactions. Some of them are related to how to consistently gauge a SU(N) group and to uniquely determine the U(1)Y gauge boson self interactions of the Standard Model. In this work we construct a consistent NCQFT based on SU(3)C × SU(3)L × SU(3)R trinification using Seiberg...

It is shown that unification of strong and Electroweak interactions at Tev scale may lead to appearance of topologically stable monopoles with masses of the order of 10 Tev. In particlular, in the realistic Petite Unification Theory (PUT) such objects appear as a result of the breakdown SU(4)⊗SU(2)3 → SU(3)×SU(2)×U(1)/Z3. Those monopoles may play an important role in the early Universe, at fini...
متن کاملHexagonal SU(3) Unification and its Manifestation at the TeV Scale
We consider SU(3)C × SU(2)AL × SU(2)BL × U(1)Y as the low-energy subgroup of supersymmetric SU(3) unification. This may imply small deviations from quarklepton universality at the TeV scale, as allowed by neutron-decay data. New particles are predicted with specific properties. We discuss in particular the new heavy gauge bosons corresponding to SU(2)AL × SU(2)BL → SU(2)L. 1 Hexagonal SU(3) Mod...
