Introduction to Vectors

3.1 Introduction to Vectors.  Vectors indicate direction; scalars do not  Examples of scalars: time, speed, volume, temperature  Examples of vectors:

Vectors. Vector and Scalar quantities Scalar quantities have size or magnitude, but a direction is not specified. (temperature, mass, speed, etc.) Vector.

VectorsVectors. What is a vector quantity? Vectors Vectors are quantities that possess magnitude and direction. »Force »Velocity »Acceleration.

Inside the Tevatron Main Ring

Detection of a top/antitop event

Top/antitop event in the D0 detector Run 92704, Event 14022

Top/antitop event in the D0 detector Run 92704, Event 14022

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!!
