Experimental implications of the dual colour solution to the generation puzzle

Abstract

Apart from offering explanations not only for the distinctive fermion mass and mixing patterns but also for the actual values of the mass and mixing parameters, the dual colour solution to the generation puzzle gives numerous detailed predictions ranging from rare FCNC meson decays and $μ$-$e$ conversions in nuclei at low energies to cosmic ray air showers with energies beyond $10^{20}$ eV at the extreme end of the experimental range. Besides, it predicts a new class of flavour-violating phenomena (called transmutations) due to the rotating fermion mass matrix which are unambiguously calculable. Comparison with experiment of these many ``parameter-free'' predictions reveals no violation of existing bounds but identifies several striking effects which can be tested with present experimental sensitivity.
