1. High Energy Physics at the University of Oregon

2. Standard Model  What is the universe made of?  How does it interact? Standard Model very successful, but incomplete…

3. Outstanding Questions What causes mass? What breaks EW symmetry? Are there additional symmetries to nature? Are there extra dimensions? Why matter (not antimatter)? What is dark matter? And many more…

9. Linear Collider (Future) e + e - -> HZ  Precise Higgs studies  Supersymmetry  Extra dimensions or ???  Precision electroweak  Interesting for new students U Oregon group is VERY involved

10. BaBar Physics High Luminosity Asymmetric e + e - 100M BB,  already! Measure CP violation Matter-antimatter Rare B decays New physics Tau lepton physics

11. CP Violation in B 0 decays Fully reconstruct one B 0 (or B 0 ) as a tag Reconstruct second B in CP eigenstate (J/  S vs. J/  L ) Time dependence => CP violation e - (9 GeV) e + (3 GeV)  = 0.56 B tag B CP zzzz ~250  m

12. Rare B Decays Forbidden in SM at tree level Highly sensitive to new physics (eg: SUSY) Measure branching fractions to 10 -6 or better Many channels, good thesis topic… b -> s  (penguins) B 0 ->    
