Steps in Analysis of Events

• Identify jets and muons and write energies in
  table.
• Measure and record angles of jets and muons
  counterclockwise from x axis.
• Draw vectors in rectangular space or on graph
  paper using head-to-tail method. Represent
  momentum of 10 GeV/c as 1.0 cm arrow.
• Neutrino energy in GeV is the length of the arrow
  you must draw in order to make the total pT 0.
• Add all of the jet, muon, and neutrino energies
  and divide the sum by two to get the top quark
  mass.
