This study explores gauge and Yukawa coupling unification within the minimal supersymmetric standard model. It reveals a unique supersymmetry spectrum distinct from prior Yukawa unification research.
Area of Science:
- High-energy physics
- Supersymmetry phenomenology
Background:
- Gauge and Yukawa coupling unification are key concepts in Grand Unified Theories (GUTs).
- Effective "mirage" mediation provides specific boundary conditions at the GUT scale.
Purpose of the Study:
- To analyze the implications of gauge and third family Yukawa coupling unification at the GUT scale for the Large Hadron Collider (LHC).
- To investigate a specific set of boundary conditions characterized as effective "mirage" mediation.
Main Methods:
- Global chi-squared (χ2) analysis incorporating various low-energy observables.
- Fitting within the minimal supersymmetric standard model (MSSM) framework.
- Fixing tanβ and μ at the weak scale while considering 10 GUT scale parameters.
Main Results:
- Good fits were achieved for low-energy experimental data.
- The predicted supersymmetry spectrum differs significantly from previous studies on Yukawa unification.
Conclusions:
- Effective "mirage" mediation with unified couplings offers a viable framework for particle physics beyond the Standard Model.
- This approach leads to novel predictions for the supersymmetry spectrum at the LHC.

This process starts with a thin layer, saturated with the drug, forming at the interface between the solid and liquid. The solute then diffuses from this layer into the main solution. The Noyes-Whitney equation suggests that the rate of dissolution relies on the diffusion...
