Organized by: Prof. Lu Lu
Events on Monday, February 9th, 2009
- Joint NPAC Forum/HEP Seminar
- New oscillation results from MiniBooNE
- Time: 4:00 pm

- Speaker: Chris Polly, University of Illinois Urbana-Champaign
- Abstract: In June 2007, MiniBooNE published results for a search for electron flavor neutrinos appearing in a predominantly muon neutrino beam. Although no excess of events was observed at an L/E consistent with a simple mixing interpretation of LSND, a > 3 sigma excess was observed at low energy. In the intervening time, MiniBooNE has acquired 3.3e20 POT delivered with the horn-focusing positively charged pions to create a predominantly antineutrino beam. The results from the recently unblinded nuebar appearance search will be discussed along with work that has transpired over the last year in understanding the low energy excess.
