The Hunt for Axion Dark Matter

Ed Daw (Sheffield University)


Abstract

Over the past few years, both direct and indirect searches for WIMPs have continued to place ever more stringent limits. In the meantime, the Higgs boson has been discovered, and the mystery of why CP is so precisely conserved in QCD remains to be solved. It is possible to draw these three threads together if the dark matter in our Universe consists of axions. I will describe a direct search for axions called ADMX, progress in running this experiment using ultra low noise squid amplifiers, and work at Sheffield on a idea to increase the search rate in cavity axion searches using a resonant feedback approach.
