WZ plus missing-ET signal from gaugino pair production at LHC7

Abstract

LHC searches for supersymmetry currently focus on strongly produced sparticles, which are copiously produced if gluinos and squarks have masses of a few hundred GeV. However, in supersymmetric models with heavy scalars, as favored by the decoupling solution to the SUSY flavor and CP problems, and mḡ ≥ 500GeV as indicated by recent LHC results, chargino-neutralino (W1±Z2) production is the dominant cross section for mW1 ∼ mZ2
