Axions were originally predicted as a dynamical solution to the strong CP problem. Axion like particles are also a generic prediction of many high energy physics models including string theory. Theoretical models for axions are reviewed, giving a generic multi-axion action with couplings to the standard model. Axion cosmology motivates the existence of several distinct populations of axions...

Presentation
To date, most direct detection searches for axion dark matter, such as those by the Axion Dark Matter Experiment (ADMX) microwave cavity search, have assumed a signal shape based on an isothermal spherical model of the Milky Way halo. Such a model is not capable of capturing contributions from realistic infall, nor from a baryonic disk. Modern N-Body simulations of structure formation can...

We report the first axion dark matter search with toroidal geometry.
Exclusion limits of the axion-photon coupling gaγγ over the axion mass range from 24.7 to 29.1 µeV at the 90% confidence level are set through this pioneering search. Prospects for axion dark matter searches with larger scale toroidal geometry are also given.
