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.
GOOD LUCK!!
