T2K And The 'Ghosts' Of Particle Physics

Thursday, February 25, 2010 - 10:50 in Astronomy & Space

The T2K (Tokai-to-Kamioka) project has tracked their first neutrino, one of the least understood particles in the universe.  The detection of the neutrino as it passed 185 miles from the East to the West of Japan means the study of the mysterious phenomenon of neutrino oscillations may shed more light on the role of the neutrino in the early universe, or perhaps even help answer questions about why there is more matter than anti-matter in the universe. "Neutrinos are the elusive ghosts of particle physics, T2K spokesperson Takashi Kobayashi said."They come in three types, called electron neutrinos, muon neutrinos, and tau neutrinos, which used to be thought to be unchanging. This is a big step forward, we've been working hard for more than 10 years to make this happen." read more
