Physics of neutrino oscillations in the three-flavor paradigm, and probes of beyond-the-SM physics using neutrino oscillations.

A brief overview of the goals of the topical group, many of which have connections with many of the other topical groups

1. Accelerator: short baseline, long baseline
2. Reactor: short baseline, medium baseline, long baseline
3. Solar
4. Atmospheric
5. Low energy astrophysical (supernova, diffuse supernova neutrino background, cosmic neutrino background, …)
6. High energy astrophysical
7. Neutrino oscillation theory

1. Atmospheric mass splitting
2. Solar mass splitting
3. Atmospheric mixing angle
4. Solar mixing angle
5. Reactor mixing angle
6. CP violating phase

1. Light steriles (~1 eV)
2. Neutrino Non-Standard Interactions (NSI)
3. Unitarity
4. Decay
5. Decoherence
6. Large Extra Dimensions (LED)
7. Lorentz Invariance Violation (LIV) / CPT violation
8. Unparticles
9. Combinations of the above

We will have a series of six short 1.5 hour meetings to discuss the present and future status of neutrino oscillations. All times are eastern time. Each meeting will have three 20 minute talks followed by 30 minutes of open discussion including mini talks by anyone who would like to. Please register in advance.
