 ===== FXS: Higgs production from SUSY cascades =====

-Consider SUSY simplified model suggested in arXiv:1703.06544, tested by CMS in SUS-16-045
+Considered SUSY simplified model suggested in [[http://arxiv.org/abs/arXiv:1703.06544|arXiv:1703.06544]], tested by CMS in [[http://cms-results.web.cern.ch/cms-results/public-results/preliminary-results/SUS-16-045/index.html|SUS-16-045]].

-Pick benchmark with light sbottom, but outside CMS exclusion: m(sbottom) = 300 GeV, m(chi02) = 280 GeV and m(chi01) = 150 GeV and generate events with Pythia 8 and test against ATLAS 8 TeV SUSY searches using CheckMATE, but also using Rivet and Contur to test effects in the higgs fiducial measurement in diphoton final state (arXiv:1407.4222, Rivet analysis ATLAS_2014_I1306615)

-== Results from Rivet and Contur ==
+//nb this is a 4leptons+MET search;\\
+nd best result is from 0-1 lepton + 3 b-jets search which has more events but less sensitivity//
-Contur reports 52% CL exclusion from high pT bin of diphoton-dijet distribution
+=== Results from Rivet and Contur ===
-{{ :2017:groups:higgs:fxsnp:atlas_2014_i1306615_d21-x01-y01.pdf }} (red line is measurement + signal)
-In addition: large contribution in fiducial selection with large MET (but large uncertainty on the measurement), see region 7 in {{ :2017:groups:higgs:fxsnp:d29-x01-y01.pdf}} (red line is signal contribution only)
+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!
