SUMMARY:Long and Longer Baseline Neutrino Oscillations: Searching for 
 Symmetry Violation\, High Energy Seminar\, Roger Wendell\, Duke Univer
 sity
DESCRIPTION:Massive neutrinos are one of the first clues that the Stan
 dard Model of particle physics is not a complete description of nature
 . Exactly how far beyond the Standard Model they are though\, is a top
 ic of continuing study. At present\, evidence for their mass in the fo
 rm of flavor oscillations has been observed in several sources and has
  established a global picture of oscillations in two primary regimes. 
 Existing data can be described in large part by mixing between two act
 ive neutrinos\, dependent upon the ratio of the neutrino flight length
  (baseline) to its energy\, L/E. The presence of the third neutrino\, 
 however\, may bridge these two regimes through the as-yet-unmeasured m
 ixing angle\, $	heta_{13}$. If $	heta_{13}$ is found to be non-zero\, 
 the door to a measurement of CP violation using neutrinos will be open
 ed. In this talk I will discuss the physics of very long baseline ($si
 m$10\,000~km) neutrino oscillations including searches for $	heta_{13}
 $ at Super-Kamiokande. I will also discuss on-going searches for $	het
 a_{13}$ at the T2K long baseline ($sim$300~km) experiment and prospect
 s for a future measurement of CP violation.
