A split SUSY model from SUSY GUT

Understand

We propose to split the sparticle spectrum from the hierarchy between the GUT scale and the Planck scale.

• A split supersymmetric model, which gives non-universal gaugino masses, is built with proper high dimensional operators in the framework of SO(10) GUT.
• Based on a calculation of two-loop beta functions for gauge couplings (taking into account all weak scale threshold corrections), we check the gauge coupling unification and dark matter constraints (relic density and direct detections).
• We find that our scenario can achieve the gauge coupling unification and satisfy the dark matter constraints in some part of parameter space.
