Cool article. If you don't mind my asking, are you on a newsgroup that sends out these articles? It seems like you always hear about the interesting physics awry stories. My poor self is too busy. Pout. Anyway, thanks for the link.

Neutrinos - always the joker in the pack!

You can find out a lot more about the research discussed in the BBC article (http://news.bbc.co.uk/hi/english/sci/tech/newsid_1660000/1660407.stm) by looking at the NuTeV Electroweak Page (http://www.pas.rochester.edu/~ksmcf/NuTeV/) (from the NuTeV Collaboration (http://www-e815.fnal.gov/)). You can also download a preprint of the technical paper: "A Precise Determination of Electroweak Parameters in Neutrino-Nucleon Scattering (http://xxx.lanl.gov/abs/hep-ex/0110059)".

The paper concludes, "In a model-independent analysis, this result suggests a smaller left-handed neutral current coupling to the light quarks than expected". This might mean anything from a small change to the standard model to a large change in the standard model, to a whole new standard model. That all remains to be seen. However, to parley this into anything remtely resembling a favorable outcome for the "electric star hypothesis" is far beyond the scope of reason. That hypothesis is so badly flawed, on obvious & fundamental levels, that no detail of neutrino experiments could ever rescue it. Besides, the particle energy involved (800 Gev protons) is vastly higher than that exhibited by solar neutrinos. There is no reason to believe that these results would have any effect on the much lower energy solar neutrinos.
