Title: Invisible axion and neutrino masses

Abstract

We show that in any invisible axion model due to the effects of effective nonrenormalizable interactions related to an energy scale near the Peccei-Quinn, grand unification or even the Planck scale, active neutrinos necessarily acquire masses in the sub-eV range. Moreover, if sterile neutrinos are also included and if appropriate cyclic Z{sub N} symmetries are imposed, it is possible that some of these neutrinos are heavy while others are light.

  • We survey mechanisms which introduce lepton-number violation into the standard model. These mechanisms involve extensions in the fermion or scalar sectors. We present a minimal model with explicit lepton-number breaking and an invisible axion. Neutrino masses are generated at one loop. For a reasonable range of parameters the model provides a solution to the strong {ital CP} and solar-neutrino problems.
  • A new type of invisible-axion model based on the recent variant axion models is presented. It belongs to the N = 1 type model and hence is free of domain-wall problems. The Peccei-Quinn-symmetry transformations are not totally generation and flavor blind which may help in understanding the small values of electron and u-quark and large t-quark masses. The light neutrino mass pattern in the two-Higgs-singlet models can have a very different hierarchy which differs from the other type of invisible-axion models.
  • We reexamine the axion-photon couplings in various invisible axion models motivated by the recent proposal of using optical interferometry at the ASST facility at the SSCL to search for the axion. We illustrate that the assignment of U(1){sub PQ} charges for the fermion fields plays an important role in determining the couplings. Several simple nonminimal invisible axion models with suppressed and enhanced axion-photon couplings are constructed, respectively. We also discuss the implications of possible new experiments to detect solar axions by conversion to x rays in a static magnetic apparatus tracking the Sun.
  • This Letter reports the results from a haloscope search for dark matter axions with masses between 2.66 and 2.81 μ eV . The search excludes the range of axion-photon couplings predicted by plausible models of the invisible axion. This unprecedented sensitivity is achieved by operating a large-volume haloscope at subkelvin temperatures, thereby reducing thermal noise as well as the excess noise from the ultralow-noise superconducting quantum interference device amplifier used for the signal power readout. Finally, ongoing searches will provide nearly definitive tests of the invisible axion model over a wide range of axion masses.
