truth study of SU3 at 10 TeV
- production quarks (1d/2d)
- production SUSY particles (1d/2d)
- BR for neutralino2|3|4 -> stau -> neutralino1
- which (s)quark above N2->ST->N1 decay
- compare to 14 TeV
masses
- inv mass: ll, qll, qlnear, qlfar, ql+, ql-, ql
- same inv masses with visible tau
- split up ll into different N2|N3|n4
  - almost no statistics for N3 and N4
  - almost no statistics for N3 and N4
qll truth study
- number of gluons/quarks in same cascade/event
- is highest pt jet in same cascade/event the correct one?
- deta, dphi, dR betwween q and ll (eta/phi plot)
reconstructed level
- inv masses
- signal combinatorics
- truth matching
- efficiency/fake rate
- trigger?
background substraction using OSSS
- how for ql and qll?
- test OSSS for QCD fakes
- asymmetric background
generate
full SU3, 14 TeV
AtlfastII SU3, SU1, SU4 (10/)14 Tev
code development
- truth model analyser/plotter
- MassEdge Calculator (calculates inv. mass edges from ISASUGRA files)
