    8282- The provided data corresponds to LHC events that contains at least two isolated leptons (lepton=electron/muon) with pT > 15. Prove it!
    83 - bla bla
    84 - The data presents an excess corresponding to a new physical state. Find the observable that makes this excess explicit.

     84- The data contains the equivalent of an integrated luminosity of 60 pb-1. I presents an excess corresponding to a new physical state. Find the observable that makes this excess explicit.
     85
     86- What is the new particle's mass?
     87
     88- What does it decay into?
     89
     90- For each decay channel, express the cross section times branching ratio as a function of the number of observed events (Nobs) the number of background events (Nb), the integrated luminosity (L) and the event selection efficiency.
     91
     92- How would you measure the background yield from this data sample?
