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

Done by: Ursula Laa

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]].

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)

=== Results from CheckMATE ===
Test: Calculation of r = signal/(95%CL limit on signal)\\
Result: Allowed\\
Result for r: 0.236342309023\\
Analysis: [[http://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/CONFNOTES/ATLAS-CONF-2013-036|atlas_conf_2013_036]]\\

//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!
