Etymology[edit]

Named by Frank Wilczek after Axion, a brand of laundry detergent, for its -on suffix and the notion that the new particle could "clean up" a problem in physics.

Noun[edit]

axion ‎(plural axions)

  1. (physics) A hypothetical subatomic particle postulated to resolve certain symmetry problems concerning the strong nuclear force.

      The axion is a candidate particle for the cold dark matter that constitutes a large fraction of the mass of the Universe.
    • 2000, Steven Weinberg, The Quantum Theory of Fields, Volume 3: Supersymmetry, page 375,
      In summary, the first version of gravity-mediated supersymmetry breaking has the advantage of giving an axion mass that is within cosmological bounds, while the second version has the advantage of giving the gauginos masses that are comparable to the masses of the squarks and sleptons.
    • 2013, Adrian C. Melissinos, Reminiscences: A Journey Through Particle Physics, page 93,
      Let us begin with a disclaimer: axions, a, have been conjectured to exist on theoretical grounds, but have not as yet been observed. They are supposed to be very light particles that interact very weakly with matter.
    • 2015, Paul Seidel (editors), Applied Superconductivity: Handbook on Devices and Applications, page 857,
      Theoretical considerations appear to indicate that the axion mass should be somewhere between the microelectron volt and millielectron volt range.
