Axions

prof. dr hab. Krzysztof A. Meissner

Wydział Fizyki UW

I will discuss theoretical motivations for the existence of axions and bounds on their masses and interactions coming from astrophysics and cosmology as well as reasons why they are natural Cold Dark Matter candidates. I will describe how the weakness of their couplings is naturally explained by the smallness of neutrino masses. I will also present existing experiments searching for axions, in particular OSQAR at CERN.
