The Weinberg Angle Without Grand Unification
We assume that strong and electroweak interactions become strong at very high energies. With this assumption, we compute the low-energy gauge coupling constants αi(mZ) as a function of the cutoff scale, taking the supersymmetric standard model with 3+2n families of quark and lepton multiplets. We find that only the five family case (n = 1) is consistent with the experimental values of the gauge...
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 کاملTowards 5D Grand Unification without SUSY Flavor Problem
[ ] Towards 5D Grand Unification without SUSY Flavor Problem Ki-Young Choi, Jihn E. Kim and Hyun Min Lee 0303213 We consider the renormalization group approach to the SUSY flavor problem in the supersymmetric SU(5) model with one extra dimension. In higher dimensional SUSY gauge theories, it has been recently shown that power corrections due to Kaluza-Klein states of gauge fields run the soft ...
متن کاملPhenomenological Aspects of Supersymmetric Standard Models without Grand Unification
When the GUT relation on gaugino masses is relaxed, the mass and composition of the lightest neutralino are different from those in the GUT case. We discuss its phenomenological implications on the relic abundance of the neutralinos and on superparticle searches. In particular, we focus on the case where the neutral component of Winos dominates the lightest neutralino. It turns out the Wino-LSP...
متن کاملLocal Grand Unification
In the standard model matter fields form complete representations of a grand unified group whereas Higgs fields belong to incomplete ‘split’ multiplets. This remarkable fact is naturally explained by ‘local grand unification’ in higher-dimensional extensions of the standard model. Here, the generations of matter fields are localized in regions of compact space which are endowed with a GUT gauge...
