NuTeV result disagrees with Standard Model

Trevor Johnson writes "New Scientist reports that physicists from the NuTev collaboration at Fermilab have announced a result on their Web page. Bombarding iron nuclei with high-energy neutrinos, they found a 99.75% chance that neutrinos interact slightly differently from the way the Standard Model (the reigning theory which describes the strong, electromagnetic, and weak forces, but not gravity) says they should. Even though the discrepancy is small, it is likely to be significant. There is no theory to explain the difference, but it could indicate a hitherto unknown force. NuTev has submitted a "Physical Review Letter" paper. There is a press release from Fermilab and a plain English version."
