What did I learn?

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.

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.
