Supersymmetric Dark Matter after Run I at the LHC: From a TeV to a PeV

TL;DR

This paper reviews the implications of LHC Run I results on supersymmetric dark matter models, exploring extensions beyond minimal models and considering higher mass scales up to PeV energies.

Contribution

It introduces extended supersymmetric models with non-universal Higgs masses and gravity-mediated scenarios with various LSP candidates, broadening the scope of viable dark matter models.

Findings

LHC Run I data pushes supersymmetry scale beyond 1 TeV.

Simple models with universal scalar and gaugino masses are increasingly constrained.

Extended models with non-universal Higgs masses and multiple parameters remain viable.

Abstract

The absence of low energy supersymmetry in run I data at the LHC has pushed the nominal scale for supersymmetry beyond a TeV. While this is consistent with the discovery of the Higgs boson at \approx 125 GeV, simple models with scalar and gaugino mass universality are being pushed into corners of parameter space. Some possibilities within the constrained minimal supersymmetric extension of the standard model (with four parameters) are discussed along with a one parameter extension in which the Higgs soft masses are non-universal. Also discussed are 2-, 3-, and 4-parameter versions of pure gravity mediated models with a wino, Higgsino, or bino LSP respectively.
