Definition of model: gluino, higgsino, $\tilde{t}_1$, $\tilde{t}_2$, and $\tilde{b}_1$ present in low energy spectrum.

See Evans et. al for pheno study of model without gluinos - http://arxiv.org/abs/1209.0764v2

2j+2j resonant (CMS)	No limit on direct stop - 300 GeV stop close to limit	CMS 7TeV. plots cuts off for m<300 GeV - why?	http://arxiv.org/abs/1302.0531
2j+2j resonant (ATLAS)	No limit on direct stop. $\sigma<100pb$ at $m=150$ GeV, $\sigma<20pb$ at $m=300$ GeV	ATLAS 7TeV.	http://arxiv.org/abs/1210.4826v2

* Kinematic regimes:

Higgsino Decoupled ($\tilde{m}_h > \tilde{m}_{t_2}, \tilde{m}_{b_1}$)
- Final State: (Z/h/W)(Z/h/W) + jets
Higgsino Present ($\tilde{m}_h < \tilde{m}_{t_2},\tilde{m}_{b_1}$)
- Final State: all hadronic, W+jets
