4. Selection description

4.1 Trigger selection

PS: This part cannot usually be described by the fast-simulation of detector.

4.2 Object definition

Explained here how the objects are defined.

4.3 Cut-flow chart

4.4 Definition of exotic observables

Like SUSY transverse observable. Notice that classical MT2 & MT2W are encoded within the MadAnalysis framework.

5. Detector simulation

Can we use the last release of the Delphes package with the CMS/ATLAS MA5tune-card? or do need to improve the simulation?

6. Validation material

Contact with CMS established. Waiting for the validation material requested

• LO/NLO? LO
• Model used: Scalar resonances, RS gravitons
• MC generator program (name + version): PYTHIA 8.2
• Shower program (name + version): PYTHIA 8.2
• Tune of Pythia: CUETP8M1
• PDF set: NNPDF2.3
