<< Hi all-
Without repeating Leigh's message, the deficiency of mu nu's is
certainly not a new result, nor is it unique to Super-K. Soudan has
also been reporting a corresponding deficiency - important because it is
a different kind of detector.
For more information you can go to

and click on the "Newsletter" or the "Neutrino Oscillation
Industry".
I am mystified as to what prompted Zanelli's posting.

And the Mystery man speaks. I originally posted this to another Physics list
where the discussion about this result was underway. Thinking it was an
interesting piece of Physics I thought list members might find it interesting
and perhaps worth discussing. If the criteria for posting is only the very
latest experimental results, then I would submit, based on what else has been
posted on this list I come the closest to meeting this unwritten rule.
However since I don't know any good jokes about PHD's and phone booths
maybe I shouldn't be posting here. However at the risk of generating more
mystery I would like to dare pose another question concerning Neutrino mixing
on the outside chance that someone may find this question more interesting
than Phd's Phone booths and what we call each other etc.
The question is: do the ratios of the various flavors of neutrino
eventually reach an equilibrium mixture after a sufficiently long path
length. The Georgi Glashow paper "Neutrinos on Earth and in Heaven" postulate
a time independent matrix to calculate the ratios of the three flavors of
neutrino after these neutrino have "traveled a great distance" However the
probability equation developed in the Super K paper does not seem to support
this at all. My own personal view is that since the in transit neutrinos are
in a superposition state there is no way an equilibrium state can be
established. Having no defined flavor until measured the equation describes a
cyclic probability for each neutrino flavor. Hopefully someone on this list
finds this interesting enough to answer even if only to tell me I am full of
S##t.

Thank you all so much
