Warped Supersymmetric Grand Unification
We construct a realistic theory of grand unification in AdS5 truncated by branes, in which the unified gauge symmetry is broken by boundary conditions and the electroweak scale is generated by the AdS warp factor. We show that the theory preserves the successful gauge coupling unification of the 4D MSSM at leading-logarithmic level. Kaluza-Klein towers, including those of XY gauge and colored H...
متن کاملSpectrum of TeV Particles in Warped Supersymmetric Grand Unification
In warped supersymmetric grand unification, XY gauge particles appear near the TeV scale along with Kaluza-Klein towers of the standard model gauge fields. In spite of this exotic low-energy physics, MSSM gauge coupling unification is preserved and proton decay is naturally suppressed. In this paper we study in detail the low-lying mass spectrum of superparticles and GUT particles in this theor...
متن کاملReconciling Supersymmetric Grand Unification
We argue that supersymmetric grand unification of gauge couplings is not incompatible with small αs, even without large GUT-scale corrections, if one relaxes a usual universal gaugino mass assumption. A commonly assumed relation M2 ≃ mg̃/3 is in gross contradiction with αs ≈ 0.11. Instead, small αs favors M2 ≫ mg̃. If this is indeed the case our observation casts doubt on another commonly used re...
متن کاملPartly Supersymmetric Grand Unification
It is shown how grand unification can occur in models which are partly supersymmetric. The particle states which are composite do not contribute to the running of gauge couplings above the compositeness scale, while the elementary states contribute the usual large logarithmns. This introduces a new differential running contribution to the gauge couplings from partly composite SU(5) matter multi...
متن کاملSupersymmetric Unification in Warped Space
Supersymmetric unification in warped space provides new possibilities for model building. I argue that the picture of warped supersymmetric unification arises naturally through the AdS/CFT correspondence from the assumption that supersymmetry is dynamically broken at a scale ≈ (10∼100) TeV, and present several fully realistic theories in this framework. In the minimal model, the bulk SU(5) gaug...
