17. “Particle Physics” in the 20th Century • The e- was discovered by Thompson ~ 1900. The nucleus was discovered by Rutherford in ~ 1920. The e+, the first antiparticle, was found in ~ 1930. The m, indicating a second “generation”, was discovered in ~ 1936. • There was an explosion of baryons and mesons discovered in the 1950s and 1960s. They were classified in a "periodic table" using the SU(3) symmetry group, whose physical realization was point like, strongly interacting, fractionally charged "quarks". Direct evidence for quarks and gluons came in the early 1970s. • The exposition of the 3 generations of quarks and leptons is only just, 1996, completed. In the mid 1980s the unification of the weak and electromagnetic force was confirmed by the W and Z discoveries. • The LHC, starting in 2007, will be THE tool to explore the origin of the breaking of the electroweak symmetry (Higgs field?) and the origin of mass itself.

20. Dijet Events at the Tevatron • The scattering of quarks inside the proton leads to a "jet" of particles traveling in the direction of, and taking the momentum of, the parent quark. Since there is no initial state Pt, the 2 quarks in the final state are "back to back" in azimuth. QuarkNet Mentor Presentation – April 24, 2002 B. Beiersdorf,QuarkNet Staff Teacher
