| + | Picked benchmark with light sbottom, but outside CMS exclusion: **m(sbottom) = 300 GeV, m(chi02) = 280 GeV and m(chi01) = 150 GeV**. Generated events with Pythia 8 and tested against ATLAS 8 TeV SUSY searches using CheckMATE, but also using Rivet and Contur to test effects in the Higgs fiducial measurement in the diphoton final state ([[http://arxiv.org/abs/arXiv:1407.4222|arXiv:1407.4222]], Rivet analysis ATLAS_2014_I1306615) | ||

| + | //nb this is a 4leptons+MET search;\\ | ||
| + | 2nd best result is from 0-1 lepton + 3 b-jets search which has more events but less sensitivity// | ||
| + | |||
| + | === Results from Rivet and Contur === | ||
| + | |||
| + | Contur reports 52% CL exclusion from high pT bin of diphoton-dijet distribution, see left plot below (red line is measurement + signal). Note, however, that Contur assumes data=SM, which is not a good approximation in this case, see the ATLAS plot on the right. | ||

| + | |||
| + | In addition: large contribution in fiducial selection with large MET, see region 7 in the left plot below (done with Rivet). Here, the red line is signal contribution only. Note that the data point in region 7 is actually not a measurement but a 95% CL limit, so this bin excludes the benchmark point! | ||
