Photo-Transmutation of Leptons

By photo-transmutation of leptons we mean photon-lepton reactions of the following type: $γl_α\longrightarrow γl_β$ with $l_α\neq l_β$, occurring as a consequence of the lepton mass matrix changing its orientation (rotating) under changing scales. In this paper, we first discuss these reactions in general terms, then proceed to the calculation of their cross sections in two specific schemes, one within the framework of the conventional Standard Model, the other being the so-called Dualized Standard Model we ourselves advocate. Although the cross section obtained is generally small the calculation reveals certain special circumstances where these reactions may be accessible to experiment, for example with virtual photons in LEP for $γe \longrightarrow γτ$, and in BEPC for $γe \longrightarrow γμ$.

CKM Matrix and Fermion Masses in the Dualized Standard Model

A Dualized Standard Model recently proposed affords a natural explanation for the existence of Higgs fields and of exactly 3 generations of fermions, while giving at the same time the observed fermion mass hierarchy together with a tree-level CKM matrix equal to the identity matrix. It further suggests a method for generating from loop corrections the lower generation masses and nondiagonal CKM matrix elements. In this paper, the proposed calculation is carried out to 1-loop. It is found first that with the method suggested one can account readily for the masses of the second generation fermions as a `leakage' from the highest generation. Then, with the Yukawa couplings fixed by fitting the masses of the 2 higher generations, one is left with only 2 free parameters to evaluate the CKM matrix and the masses in the lowest generation. One obtains a very good fit to the CKM matrix and sensible values for the masses of $d$ and $e$, though, for a valid reason, not of $u$. In addition, the fitted values of the Yukawa couplings and vacuum expectation values of the dual colour Higgs fields show remarkable features perhaps indicative of a deeper significance.

Post-GZK Air Showers, FCNC, Strongly Interacting Neutrinos and Duality

A review is given on the recently proposed idea that air showers with energy $> 10^{20}$ eV beyond the Greisen-Zatsepin-Kuz'min cut-off may be due to neutrinos having acquired a strong interaction at these energies, as suggested by the Dualized Standard Model. Such a hypothesis is shown to be consistent with the so far known facts. Further, by linking the astrophysical puzzle of post-GZK air showers through electric-magnetic duality to the problem of fermion generations in particle physics, one obtains on the one hand estimates for the rates of some flavour-changing neutral current decays which are accessible to experiments being planned, and on the other direct tests on the hypothesis performable by new air shower detectors such as Auger. The suggestion does not exclude other explanations for post-GZK showers given in the literature. However, we diagree with a recent paper by Burdman, Halzen and Gandhi which sweepingly claimed to have excluded nearly all explanations by new particle physics including ours.

Possible Test for the Suggestion that Air Showers with $E > 10^{20}$ eV are due to Strongly Interacting Neutrinos

The suggestion is made that air showers with energies beyond the Greisen-Zatsepin-Kuz'min spectral cut-off may have primary vertices some 6 km lower in height than those of proton initiated showers with energies below the GZK cut-off. This estimate is based on the assumption that post-GZK showers are due to neutrinos having acquired strong interactions from generation-changing dual gluon exchange as recently proposed.
