Description |
The Peccei-Quinn mechanism remains the most promising way to explain CP conservation in QCD. The prediction of a new very weakly interacting boson, closely related to the neutral pion, is a testable consequence. These "axions" are an excellent cold dark matter candidate if their mass is in the micro-eV range. These may survive as a classical condensate from the early universe and can be found by ongoing direct search experiments. The motivation for axions, their cosmological and astrophysical role, and the ongoing searches will be reviewed in this talk. |
