  In this review, we discuss the role of the various experimental programs
taking part in the broader effort to identify the particle nature of dark
matter. In particular, we focus on electroweak scale dark matter particles and
discuss a wide range of search strategies being carried out and developed to
detect them. These efforts include direct detection experiments, which attempt
to observe the elastic scattering of dark matter particles with nuclei,
indirect detection experiments, which search for photons, antimatter and
neutrinos produced as a result of dark matter annihilations, and collider
searches for new TeV-scale physics. Each of these techniques could potentially
provide a different and complementary set of information related to the mass,
interactions and distribution of dark matter. Ultimately, it is hoped that
these many different tools will be used together to conclusively identify the
particle or particles that constitute the dark matter of our universe.
