  1. String Axiverse

    hep-th 2009-05 unverdicted novelty 7.0

    String theory predicts an axiverse of ultralight axions whose effects on CMB polarization, matter power spectrum, and black hole superradiance can be probed by future astrophysical experiments.

  2. Ultralight Dilatonic Dark Matter

    hep-ph 2025-06 unverdicted novelty 5.0

    Supersymmetry can stabilize an ultralight dilaton dark matter candidate, but gravity restricts its Standard Model couplings to undetectable levels, making consistent model building involved.

  3. Axions as Dark Matter, Dark Energy, and Dark Radiation

    hep-ph 2025-09 unverdicted novelty 2.0

    A mini-review of axion phenomenology showing how light bosons can account for dark matter, drive cosmic acceleration, or contribute to relativistic backgrounds in the early and late Universe.

  4. The landscape of QCD axion models

    hep-ph 2020-03 unverdicted novelty 2.0

    Review classifies QCD axion models extending the standard mass-coupling window and updates bounds from cosmology, astrophysics, and experiments.
