KnowraAxionLinked fromLinked fromThe 8 pages that link to Axion, each with the reason it gives.All 8Broader topic 5Related 3Dark matterBroader topic: Experiments search for axions through their possible conversion into photons in magnetic fields.Cold dark matterRelated: Cosmological axions could form cold dark matter despite having very different properties from WIMPs.Strong CP problemBroader topic: It dynamically drives the effective QCD angle toward zero.Frank WilczekRelated: Wilczek independently proposed the axion while studying how the strong interaction could preserve CP symmetry.QCD vacuumRelated: An axion field could dynamically relax the effective QCD vacuum angle.Hypothetical particleBroader topic: It was proposed to explain a symmetry puzzle and could account for dark matter.Hypothetical particle physics modelsBroader topic: It is a specific new-particle proposal that could also contribute to dark matter.Physics beyond the Standard ModelBroader topic: The Peccei–Quinn solution predicts an axion that experiments can seek.
