11. 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 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.
