You're baiting again, aren't you? The whole reason SNO was constructed is because it is sensitive to all three flavors of neutrino, and it uses three independent reactions as a cross-check. Previous detectors were only sensitive to electron neutrinos.
P.S. Did they really detect one-third of the amount predicted? I have read it was around 1%,
I'm afraid your source was in error.
which may be cosmic rather than solar,
Can't be. SNO (and some of the other experiments before it) can reconstruct the direction of the incident neutrinos. They can actually use them to produce a neutrino image of the sun:
and that's why they came up with the flavor change theory in the first place.
No, the flavor-change idea was inspired by the Cabibbo-Kobayashi-Maskawa quark mixing matrix, which was discovered in the 1970's. Once that was in place, it was realized that if neutrinos had mass (which was always an open possibility) they would necessarily mix in a similar fashion to the way quarks mix.
Oh, for Pete's sake, not the Cabibbo-Kobayashi-Maskawa quark mixing matrix again. Always with the Cabibbo-Kobayashi-Maskawa quark mixing matrix...are you referring to the 3x3 unitary matrix V operating on the charge -e/3 quark mass eigenstates (d, s, and b), that Cabibbo-Kobayashi-Maskawa quark mixing matrix?
I have no idea what any of this means but it sounds like some serious sh*t...
Finally something I understand.
That's the bartenders guide on Deep Space Nine, right?
