SU(7) SUSY GUTs with a natural intermediate scale
We investigate the SU(N) supersymmetric Grand Unified Theories with “custodial symmetry” mechanism to explane the doublet-triplet hierarchy. We show that in such type of SU(7) SUSY theory intermediate scale appears naturally and the correct value for sinθW is predicted via vector-like matter superfields splitting. The unification appears to be closed to MP l for all the reasonable values of αs ...
متن کاملNatural SUSY Dark Matter: A Window on the GUT Scale
One of the key motivations for supersymmetry is that it provides a natural candidate for dark matter. For a long time the density of this candidate particle fell within cosmological bounds across much of the SUSY parameter space. However with the precision results of WMAP, it has become apparent that the majority of the SUSY parameter space no longer fits the observed relic density. This has gi...
متن کاملFlavor Mediation Delivers Natural SUSY
If supersymmetry (SUSY) solves the hierarchy problem, then naturalness considerations coupled with recent LHC bounds require non-trivial superpartner flavor structures. Such “Natural SUSY” models exhibit a large mass hierarchy between scalars of the third and first two generations as well as degeneracy (or alignment) among the first two generations. In this work, we show how this specific beyon...
متن کاملSUSY and SUSY Breaking Scale at the Linear Collider
After summarising very briefly the key features of different model predictions for sparticle masses and their relation with the supersymmetry (SUSY) breaking scales and parameters, I discuss the capabilities of an ee Linear Collider (LC) with √ s ≥ 500 GeV for precision measurements of sparticle properties. Then I focus on the lessons one can learn about the scale and mechanism of SUSY breaking...
متن کاملDark Matter and the SUSY Mass Scale
The connection between the present density of neutralinos that are left over from the Big Bang and the superparticle mass scale is briefly reviewed. Superparticle mass scales in the range from a few GeV to several TeV can lead to an acceptable density of thermal relic neutralinos, the actual value depending on relations between the masses of certain sparticles and Higgs bosons. To appear in the...
