Reconciling 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...

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...

Partly 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...

Supersymmetric Grand Unification with a Fourth Generation?

The possibility of incorporating a chiral fourth generation into a SUSY-GUT is investigated. Precision fits to electroweak observables require us to introduce light supersymmetric particles, with masses less than MZ . These particles might also provide decay channels for the fourth generation quarks of mass ∼ 100 GeV. We also require tan β to lie in the range 1.50 ∼ tan β ∼ 1.75 and obtain an u...
