Abstract: (Elsevier)
Light pseudo-Goldstone bosons, with mixed CP quantum numbers leading to scalar couplings, can arise naturally in extensions of the standard model. We study several models in detail, including supersymmetric and flavour symmetric theories containing invisible axions and these new objects. They yield new phenomenological implications: (1) potentially detectable long-range forces; (2) quark and lepton masses and mixing angles sensitive to the classical background field; (3) finite gauge-coupling renormalizations in classical fields; and (4) ƒ axion can be raised to 10 15 GeV by resonant de-excitation. The possibility of experimental detection of variations in masses, charges and mixing angles is discussed in some detail.- POSTULATED PARTICLE: GOLDSTONE PARTICLE
