ADMX overview and new limits on axion mass

Axions are hypothetical elementary particles that may help~provide the answer as to why QCD preserves the discrete symmetries P~and CP. Light axions also have properties that make them ideal dark-matter~candidates. The Axion Dark Matter eXperiment (ADMX), has been at the~forefront of the search for dark-matter axions for over a decade, and over the past few years has undergone~upgrades to dramatically improve its sensitivity. 2014 was a particularly exciting year for ADMX as we collected the first production data from this new generation of the experiment.~I will discuss the data set, go over the analysis method, and present new exclusion limits on the axion mass.
