Neutrino Physics

First T2K event in the Super-Kamiokande detector.

The T2K experiment in Japan has recorded its first long-baseline neutrino event in the Super-Kamiokande detector, announced by a press release from KEK, the Japanese high energy physics laboratory. In this experiment, a beam of neutrinos is created at the new J-PARC accelerator facility in Tokai, Japan and sent 295 km to the Super-Kamiokande detector. The experiment is poised to make the first ever observation of the appearance of electron neutrinos from a quantum mechanical flavor oscillation of muon neutrinos. Boston University participants in T2K include: Professors Ed Kearns, Jim Stone, and Larry Sulak, postdoctoral associate Jen Raaf, and graduate students Mike Litos and Fanny Dufour, now at the University of Geneva.
