pMSSM SUSY and the ATLAS Z+jets+MET Excess

Abstract

A possible explanation of the excesses observed by ATLAS in the Z+jets+MET channel within the p(henomenological)MSSM is discussed. We have found that the cascade of first/second generation squarks to binos to Higgsino LSPs, with judiciously chosen sparticle masses, can provide a viable scenario that is consistent with all other experimental constraints.
