CAST: from Solar to Dark Matter Axions searches

*/ /*-->*/ CERN’s Axion Solar telescope (CAST) has been running since 2003 searching for the axion: a hypothetical particle introduced in 1978 as a consequence of the Peccei-Quinn mechanism aiming to solve the strong CP problem, i.e why is the…

Searching for axions: old and new ideas

QCD, the theory of strong interactions allows the violation of CP symmetry that would result in a non-zero value for the neutron electric dipole moment. Current measurements constrain the neutron EDM to be one trillionth of the size predicted by QCD…

Search for axions in streaming dark matter

    Streaming dark matter (DM) axions may be the better source for their discovery than the widely assumed isotropic DM. Because, a large axion flux enhancement can take place, temporally, due to gravitational lensing when the Sun and/or a planet…
