3. Selection description

3.1 Trigger selection

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

3.2 Object definition

Explained here how the objects are defined.

3.3 Cut-flow chart

3.4 Definition of exotic observables

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

3. 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?

4. Validation material

4.1 Monte-Carlo samples

• LO/NLO? NLO for simplified models of DM, LO for EFT
• Model used: Models with DM pair-produced (vector/axial-vector mediator, EFT, high-mass scalar resonance), DMsimp
• MC generator program (name + version): MG5_aMC@NLO v2.4.3 for DMsimp, MG5_aMC@NLO v2.2.3 for EFT, Powheg-Box v1 for high mass scalar resonance
• Shower program (name + version): Pythia v8.212 for DMsimp, Pythia v8.186 for EFT, Pythia v8.210 for high mass scalar resonance
• Tune of Pythia: A14, AZNLO for high mass scalar resonance
• PDF set: NNPDF3.0, CT10 and CTEQ6L1 PDF for high mass scalar resonance
• ME/PS merging????
