Title: Minimal Supersymmetry at the start of LHC Run 2:  Is it still "just around the corner"?

Speaker: Prof. Rick Cavanaugh, CERN
 

Abstract: Throughout the speaker's career, minimal Supersymmetry (SUSY) has been perpetually "just around the corner" with community interest coming and going like ocean tides.  However, with the discovery of a puzzlingly light Higgs boson near 125 GeV at the Large Hadron Collider, renewed interest in SUSY has blossomed like never before. I will present a recent analysis by the MasterCode Collaboration of a phenomenological Minimal Supersymetric Extension to the Standard Model (pMSSM10), in which 10 soft SUSY-breaking parameters are specified independently at a mass scale near the electroweak scale. By sampling over 10^9 parameter space points, we confront the pMSSM10 in a statistically meaningful way using all relevant SUSY searches at the LHC, Higgs mass and rate measurements, SUSY Higgs exclusion bounds, measurements of B-physics observables, EW precision observables, the cold dark matter (DM) relic density, and searches for spin-independent DM scattering.  I will compare the pMSSM10 to other models described by fewer parameters, like the CMSSM and NUHM, and I will also discuss some of the corresponding predictions for sparticle masses at Run 2 and future colliders.  Finally, I will describe how future LHC and direct DM searches can complement each other in the exploration of the different DM mechanisms within these Supersymmetry scenarios.
