pMSSM SUSY and the ATLAS Z+jets+MET Excess
Thomas G. Rizzo
TL;DR
This paper explores a pMSSM-based scenario where squark decay cascades can explain the ATLAS Z+jets+MET excess while remaining consistent with other experimental data.
Contribution
It proposes a specific sparticle mass configuration in the pMSSM that accounts for the observed excesses in the ATLAS Z+jets+MET channel.
Findings
A viable sparticle mass spectrum explains the excess.
The scenario is consistent with existing experimental constraints.
The decay cascade involves squarks, binos, and Higgsino LSPs.
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.
