 Doubling Up on Supersymmetry in the Higgs Sector / Ellis, John ; Quevillon, Jérémie ; Sanz, Verónica We explore the possibility that physics at the TeV scale possesses approximate $N = 2$ supersymmetry, which is reduced to the $N=1$ minimal supersymmetric extension of the Standard Model (MSSM) at the electroweak scale.
