What is "axions"

Usage examples of "axions".

And there'll be new technology for new and better observational instruments, detectors for dark matter concentrations, axions, gravity waves, and neutrinos, for instance, that will need to be built, using the new engineering techniques.

Do you remember that back in 1983 Paul Sikivie at the University of Florida suggested that if axions existed, they could be converted to photons by a big magnetic field?

The axions, which are more or less at rest in the cosmic background reference frame, are moving through my apparatus at about 1/800 of the speed of light.

So although we can't directly detect either the axions or the particles they're converted into, whatever those are, we can detect the momentum change of the conversion process.

They're the cold dark matter school, axions and photinos and gravitinos, and they don't give the right lumpiness to the Universe, either.

The search for exotic particles such as "hot" neutrinos and "cold" photinos and axions will tell us about the far future of the universe.

Candidates included heavy neutrinos, axions, a catch-all termed "weakly interacting massive particles," or "WIMPS," photinos, strings, superstrings, quark nuggets, none of which had been observed, but had emerged from attempts at formulating unified field theories.
