---++ Background study

   * Samples used in the analysis: <br />  
     <img src="%ATTACHURLPATH%/datasets2.png" alt="datasets2.png" width='775' height='690' />


We select events with two oppositely charged high pt isolated leptons requiring
   * pt > 35 & abs(eta) < 2.4 & (caloIso+trackIso)/pt < 0.15 for the muons
   * pt > 20 & abs(eta) < 2.4 & (caloIso+trackIso)/pt < 0.15 for the electrons

A distance deltaR > 0.4 between the leptons is also imposed. The events passing the selection requirements are used to construct a [[http://en.wikipedia.org/wiki/Transverse_mass][transverse mass]].

   * Transverse mass distribution after selection: <br />

---++ Jets' multiplicity study

   * Distribution of Jets for the Zprime and TTbar: <br />

   * Selection of events after doing different cuts in the Jet's multiplicity: <br />
