HEP - ASTRO SEMINAR | New Antineutrino Oscillation Results from the T2K Experiment

One of the most promising investigations of beyond-the-Standard-Model physics has been the study of neutrino oscillation, that is, the conversion of neutrinos from one flavor to another as they propagate. While neutrino oscillation is studied in a wide variety of experiments, accelerator based experiments, such as T2K, use a muon neutrino or antineutrino beam as a probe. This talk will describe the first results from T2K for antineutrino disappearance, a test of non-standard matter interactions, and the initial search for electron antineutrino appearance. In particular, the presence of electron antineutrino appearance transition is a necessary requirement for future CPV experiments with neutrinos, and has not been observed yet.
