TL;DR

This paper investigates how high-dimensional operators in E_6 SUSY GUT models influence supersymmetry breaking scalar masses and trilinear soft terms, providing insights into potential experimental distinctions between mSUGRA and GmSUGRA scenarios.

Contribution

It systematically analyzes supersymmetry breaking parameters in various symmetry-breaking patterns of E_6 SUSY GUT models with high-dimensional operators.

Findings

Scalar and gaugino mass relations can be preserved from GUT to electroweak scale.

Distinguishing mSUGRA and GmSUGRA scenarios is possible through superparticle spectrum measurements.

The study covers multiple symmetry-breaking patterns within the E_6 SUSY GUT framework.

Abstract

In the GmSUGRA scenario with the high-dimensional operators containing the GUT Higgs fields, we systematically studied the supersymmetry breaking scalar masses, SM fermion Yukawa coupling terms, and trilinear soft terms in the E_6 SUSY GUT model where the gauge symmetry is broken down to the SO(10)\tm U(1) gauge symmetry, SU(3)_C\times SU(3)_L \times SU(3)_R gauge symmetry, SU(6)\times SU(2)_a (a={\rm L,R,X}) gauge symmetry, flipped SU(5) gauge symmetry etc. In addition, we considered the scalar and gaugino mass relations, which can be preserved from the GUT scale to the electroweak scale under one-loop RGE running, in the SU(3)_C\times SU(3)_L \times SU(3)_R model arising from the E_6 model. With such relations, we may distinguish the mSUGRA and GmSUGRA scenarios if we can measure the supersymmetric particle spectrum at the LHC and ILC.
