One could be forgiven for finding the news from Neutel 11 a little disappointing, with many inconclusive results being announced, but it is still early days for precision neutrino physics and this has to be one of the most exciting conferences of the year.
Yesterday's blog updates include this short exchange between Carlo Rubbia and the neutrino physicist Altarelli. Altarelli is of course thinking about CPT violation, and Carlo Rubbia is understandably reluctant to introduce something so ugly into apparently local physics. Hello there, people! As we keep trying to explain, you can quantitatively account for the MINOS results without invoking an ugly CPT violation. It's simple. You just have to give up the idea that an antineutrino is the antiparticle of a neutrino. It's really a mirror neutrino.
