We explore the impact of current (7+8 TeV) and future (14 TeV) LHC searches on the range of viable sparticle spectra within the 19/20 – dimensional pMSSM. Considering both neutralino and gravitino LSPs, we compare our results with simplified model exclusion limits and describe important cases where the pMSSM results differ significantly from the simplified model descriptions. We also consider...

In this talk I will outline the regions of Natural Supersymmetry that are still viable after the 8~TeV LHC. In these regions of parameter space the Higgsinos are the lightest supersymmetric states with GeV scale mass splittings. I will show that such compressed states can be probed at the LHC in the j+dilepton+MET channel.

Naturalness, or fine-tuning, is one of the primary motivations for the weak-scale supersymmetry (SUSY). We argue that the presence of light higgsinos, rather than often-cited light stops, is the most basic consequence of SUSY naturalness. We'll discuss capabilities of LHC14 to probe light higgsinos in existing search channels and introduce novel, more efficient, signatures.

The recently discovered Higgs Boson allows for novel search strategies for "natural" supersymmetric particles whose decay produces Higgs bosons. In particular, searches for associated higgs production provides significant limits on stops, chargino, and neutralino masses. Various accessible final states can result, notably the di-photon channel where the narrow Higgs resonance provides a clean...

Successful models of Pure Gravity Mediation (PGM) with radiative electroweak symmetry breaking can be expressed with as few as two free parameters which can be taken as the gravitino mass and tan β. These models easily support a 125-126 GeV Higgs mass at the expense of a scalar spectrum in the multi-TeV range and a much lighter wino as the lightest supersymmetric particle. In these models,...

I will discuss an approach for the presentation of experimental constraints on supersymmetric scenarios. It is a triangle based visualization that extends the status quo wherein LHC results are reported in terms of simplified models under the assumption of 100% branching ratios. I will show that the (re)interpretation of LHC data on triangles allows the extraction of accurate exclusion limits...
