Neutrinos and Supernovae IV

Well, I really am a bit slow. The last time I mentioned Graham D's analysis of the neutrino cosmology, I failed to notice one of his main points: since a given neutrino has a different mass to the antineutrino, and they cannot annihilate, one supposes that the Koide masses are exactly halved into left and right handed annihilating particles. This allows us to view the CMB photons at $2.7$ K straightforwardly as annihilating pairs. The six Koide masses are thus assumed to label $12$ chiral neutral particles.

Neutrino and antineutrino beams at MINOS, and elsewhere, are thus viewed as mixed particles. The CMB coincidence then strengthens the premise that mass differences will not be found for the charged lepton antiparticles, which only occur with chirality. It also makes the neutrinos look more like the quarks, each coming in $12$ types, and is thus less surprising that neutrino and quark mixing shows similarities.

It seems that Graham D has been busy, trying to recover a number of basic astronomical parameters, so we should wish him and the other astronomers the best of luck with this endeavour! Other people I know are also busy studying the new cosmology, in an earthly laboratory setting.

    The resulting observations, in conjunction with other measurements of solar neutrino oscillations, disagree with the standard model with its three flavors of neutrinos. Thus, if the LSND results are correct, some fascinating new physics has been discovered.

    updated results on their antineutrino runs – a direct test of LSND. Fascinatingly, to me, they have found a different result from the neutrino one, with an oscillation probability resembling that found by LSND!

    This different mass between matter and antimatter is interesting.

  2. Ulla, this post is not about LSND etc. Please try to stay on topic.
