From: YKhan on 1 Jun 2010 01:46 Physicists observe change in neutrinos, unlocking mystery of subatomic particle - latimes.com "The new finding is important because in the theories now used to explain the behavior of fundamental particles, called the Standard Model, neutrinos have no mass. But if they have no mass, they cannot oscillate between muon and tau forms. The fact that they do oscillate indicates that they have mass and that the fundamentals of the Standard Model need some reworking, at the very least." http://www.latimes.com/news/science/la-sci-neutrino-20100601,0,1778648.story

Are we getting into "string theory"? Vibrating rather than spinning? Are these real observations or created by?? TreBert

The SM arrives wrong. The Higgs mechanism is a jury-rig to confer mass given 26 inserted parameters, http://math.ucr.edu/home/baez/constants.html There will be no Higgs boson at teh LHC because there is no Higgs mechanism - the SM is wrong. http://arxiv.org/abs/1001.4528 http://physics.aps.org/articles/v3/14 http://physics.aps.org/articles/v2/106 The Higgs boson is already excluded. While we are here... <http://en.wikipedia.org/wiki/Digital_physics#Wheeler.27s_.22it_from_bit.22> John Wheeler's "it from bit" One wonders if that is not an even more awful pun given that substitution of all instances of "t" (time) to "it" [sqrt(-1)] in a quantum field theory whose Lagrangian has a few coupling constants is a Wick rotation imposing a frequency cutoff (ignoring effects of fields varying on distance scales shorter than the cutoff). -- Uncle Al http://www.mazepath.com/uncleal/ (Toxic URL!

For at least 15 years, researchers have been collecting evidence that they can change (or oscillate) from one flavour to another. Whereas neutrinos were originally thought to have no mass, such oscillations would imply that they do, a finding that would have significant consequences for cosmology and for the standard model of particle physics". "While analyzing data from 2008 and 2009, the Gran Sasso team found that one among billions of muon neutrinos beamed towards the lab from CERN, Europe's particle-physics facility near Geneva, Switzerland, had turned into a tau neutrino by the time it reached the Opera detector". |
