Abstract
The axion is a hypothetical
elementary particle whose existence would explain the unexpected absence
of CP violation in strong interactions. Its properties also make it
a good dark-matter candidate. Although dark-matter axions could account
for the majority of mass in the universe, they are extraordinarily difficult
to detect. Groups around the world deploy exquisitely sensitive axion
detectors, each one is an elegant instrument and beyond state-of-the-art
in novel ways. This colloquium will review the role of the axion in
particle and astrophysics and will explore the various methods employed
in the search.
