Axiones are hypothetical particles proposed in theoretical physics, particularly in the context of quantum chromodynamics (QCD). They are introduced to explain the strong CP problem, which involves the observed symmetry in the strong nuclear force and the lack of observed violations. Axiones are predicted to be very light and electrically neutral, making them difficult to detect. In addition to their role in particle physics, axiones are also considered as potential candidates for dark matter. Their unique properties could help scientists understand the composition of the universe and the nature of dark matter, which remains one of the biggest mysteries in cosmology.
