We are doing extremely well! • AIP’s Ten Top Physics Stories for 2007 • Three out of ten are from HEP: • The Energy Frontier: The Tevatron • in its quest to observe the Higgs boson, updated the top quark mass and observed several new types of collision events, such as those in which only a single top quark is made, and those in which a W and Z boson or two Z bosons are made simultaneously. http://www.aip.org/pnu/2007/split/821-1.html • The Intensity Frontier: The MiniBooNE Experiment • solves a neutrino mystery, apparently dismissing the possibility of a fourth species of neutrino.http://www.aip.org/pnu/2007/split/820-1.html • The Cosmic Frontier: The Auger Observatory • Based on data recorded at the Auger Observatory, astronomers conclude that the highest energy cosmic rays come from active galactic nuclei. http://www.aip.org/pnu/2007/split/846-1.html

Physics of Flavor • Flavor phenomena • Essential to shaping physics beyond the SM. • SM is incomplete: • Neutrino Masses (flavor) • The only new physics seen so far in the laboratory • Baryon Asymmetry of the Universe (flavor) • Dark Matter • Dark Energy • Inflation
Neutrinos The enigmatic neutrinos are among the most abundant of the particles that make up our universe. To understand the universe, must understand neutrinos. Behavior is so different from other particles. Opening a “new” window
Neutrinos • Neutrino masses • via the See-Saw mechanism, point to new physics at a very high mass scale (unification scale). • Baryon Asymmetry of the Universe • Possible scenarios as the source • Electroweak baryogenesis – LHC and ILC. • Leptogenesis – Neutrino CP violation would support it. • The Four Measurements • value of sin22q13 • Are neutrino masses Dirac or Majorana? • Is the mass ordering normal or inverted? • CP violation
