Non-universal SUGRA at LHC: Prospects and Discovery Potential

TL;DR

This paper investigates non-universal SUGRA models that can explain the observed Higgs mass and dark matter constraints, identifying promising signatures for SUSY discovery at the 14 TeV LHC.

Contribution

It presents specific benchmark points in non-universal SUGRA parameter space consistent with Higgs mass and dark matter, highlighting discovery channels at the LHC.

Findings

Third family squarks can be lighter than first two in viable models.

Bottom-rich and leptonic final states offer promising discovery prospects.

Certain benchmark points are compatible with current constraints and detectable at 14 TeV LHC.

Abstract

We explore supersymmetry (SUSY) parameter space with non-universal high scale parameters in gravity mediated SUSY breaking (SUGRA) scenario that accommodates a Higgs mass of (125$\pm$2) GeV while satisfying cold dark matter relic density and other low energy constraints. We indicate a few benchmark points consistent with different dark matter annihilation processes where third family squarks are lighter than the first two as a requirement to keep the Higgs mass within the limit. We show that bottom rich and leptonic final states have better reach in such parameter space points and is the most likely scenario to discover SUSY at the upcoming run of LHC with center-of-mass energy 14 TeV.
