 - The provided data corresponds to LHC events that contains at least two isolated leptons (lepton=electron/muon) with pT > 15. Prove it!

-- The data presents an excess corresponding to a new physical state. Find the observable that makes this excess explicit.

+- 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. 
+
+- What is the new particle's mass? 
+
+- What does it decay into? 
+
+- 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. 
+
+- How would you measure the background yield from this data sample?
