Request Description and Potential
Reason for request:
Stealth supersymmetry models can evade traditional missing E_T signatures. One model adds a singlet S coupled to vectorlike quarks, as discussed in arxiv:1105.5135 and 1201.4875. A decay chain squark -> quark + bino, bino -> photon + singlino, singlino -> singlet + gravitino, singlet -> gluon gluon then leads to diphoton + jets signatures. This model appears to be constrained by this search, as modeled in 1201.4875, but an official recasting of the results would be useful.
