Evidence for Neutrino Disappearance

decowski writes "Results from the first six months of experiments at KamLAND, an underground neutrino detector in central Japan, show that anti-neutrinos emanating from nearby nuclear reactors are "disappearing," which indicates they have mass and can oscillate or change from one type to another. As anti-neutrinos are the anti-matter counterpart to neutrinos, these results provide independent confirmation of earlier studies involving solar neutrinos and show that the Standard Model of Particle Physics, which has successfully explained fundamental physics since the 1970's, is in need of updating. The results also point the way to the first direct measurements of the total radioactivity of the earth."

Minor quibble, or addendum

I think it's been suspected since 1995 when the Brookhaven Muon g-2 experiment results began to get published, and very clear since 1998 or so, as they expanded and were corroborated, that there are defects, omissions, from the Standard Model that go beyond the little detail of overlooking gravitation.

Check out this search for more info on the anomalous magnetic moment of the muon.

Whoops... swap former and latter.

Neutrinos require mass assumption; g-2 requires supersymmetry or other extension.
