== 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 ===

Event Selection:

*  Two same flavored lepton with opposite electric charge  ( that pass lepton selection?)
*  el[0] pt > 25 and el[1] pt >20
*  mu[0] pt > 20 and mu[1] pt > 20
*  dilep m = 91.1876( +- 0.0021) +- 15 
*  dilep pt > 60 

*  events having more than one jet with pT > 30 GeV - remove 
*  b-tagged jet Veto : at least one bjet pt > 20, |eta| < 2.4 - remove
*  if el[2 onwards] pt > 10 -remove
*  if mu[2 onwards] pt > 5 -remove
*  if tau pt >18 - remove

After optimization:
*  MET > 100
*  Delta phi ( dilep.pt , ptmiss) > 2.6 rad 
*  |MET - dilep.pt| / dilep.pt  < 0.4

=== 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?
*   Model used:
*   MC generator program (name + version):
*   Shower program (name + version):
*   Tune of Pythia:
*   PDF set:
*   ME/PS merging????

=== 4.2 Reference plots / cut-flows ===
