    Could ‘Mirror Neutrons’ Account for Unobservable Dark Matter?

    Could mirror universes or parallel worlds account for dark matter — the ‘missing’ matter in the Universe? In what seems to be mixing of science and science fiction, a new paper by a team of theoretical physicists hypothesizes the existence of mirror particles as a possible candidate for dark matter. An anomaly observed in the [...]

    Fraser. The gentlemen have determined that "the loss rate of slow moving neutrons (a weak decay) depends upon the strength and direction of a magnetic field applied". That is a a parity effect. All weak interactions show parity effects. They are universally seen. When T.D.K.Lee and C.N. Yang searched the literature in the fifties, they found that nobody had ever checked. After the Wu, Ambler experiments at the National Bureau of Standards showed they were apparently correct, and people went back to archived records of experiments that had been done and would have shown the effect also, they found that the effect was present in not only every experiment, but in every run of every experiment, and occasionally also seen in some strong interactions...(Martin Gardner, Mirror Asymmetry and Time Reversed Worlds".) pete

    There is something else to be said about their original discovery,though. One of our forum members made a post wherein he said that an atom changed it's parity when it absorbed or emitted a photon,from odd to even, or vice-versa (I think it was either Tensor or Grey...both of whom know lots of the intricate physics I'm still learning)....regardless, it opens up a new interpretation of the original interpretation of the Tau-Theta puzzle.
    Sensitive measures of the mass of the neutral K meson show that there is a slight difference in the masses of the "long" and the "short" variants of ~ 3.5 X 10-6 eV. Decays of the K meson can occur via two or three pions, with one branch being even parity and the other odd....implying parity is not conserved here. However, kaon decays occur in the presence of the ambient neutrino sea. The sea can interact via the three branches of the weak force, the W+, the W-, or the Z0, with the kaon during it's decay. As I've tooted before, the Z can be any particle antiparticle pair, including photon/anti-photon (it is it's own antiparticle), and neutrino/antineutrino pair.. (Gamow's graviton). If the kaon experiences this weak neutral current as it decays, the absorption of the pair will change it's wavefunction's parity , and the subsequent decay cannot match that of the 'free' kaon, causing an apparent failure of parity conservation. The neutrino/antineutrino pair can annihilate as a photon, be incorporated in the kinetic energy of the daughter pions or separate into the sea....and in this case parity is still conserved.
    Fortunately, this quantum gravitational effect is testable. The two rates for three pion, and two pion, decays should vary for a small kaon beam source pointed at a spallation source of neutrinos ....a nuclear reactor. If so,that would give me a second physical effect both predicted and seen. pete


    some work on k mesons decaying with nu/anti-nu pairs has been done....SEE: http://arxiv.org/abs/0903.0030
