Contribution

It provides a phenomenological analysis of how intermediate scale physics modifies the MSSM spectrum and related observable consequences.

Findings

Modified low energy spectrum due to intermediate scale fields

Altered collider phenomenology predictions

Changed dark matter relic density calculations

Abstract

The presence of fields at an intermediate scale between the Electroweak and the Grand Unification scale modifies the evolution of the gauge couplings and consequently the running of other parameters of the Minimal Supersymmetric Standard Model, such as gauginos and scalar masses. The net effect is a modification of the low energy spectrum which affects both the collider phenomenology and the dark matter relic density.
