The details of what constitutes the majority of the mass that makes up dark
matter in the Universe remains one of the prime puzzles of cosmology and particle
physics today-80 y after the first observational indications. Today, it is widely
accepted that dark matter exists and that it is very likely composed of
elementary particles, which are weakly interacting and massive [weakly
interacting massive particles (WIMPs)]. As important as dark matter is in our
understanding of cosmology, the detection of these particles has thus far been
elusive. Their primary properties such as mass and interaction cross sections are
still unknown. Indirect detection searches for the products of WIMP annihilation
or decay. This is generally done through observations of ?-ray photons or cosmic
rays. Instruments such as the Fermi large-area telescope, high-energy
stereoscopic system, major atmospheric gamma-ray imaging Cherenkov, and very
energetic radiation imaging telescope array, combined with the future Cherenkov
telescope array, will provide important complementarity to other search
techniques. Given the expected sensitivities of all search techniques, we are at
a stage where the WIMP scenario is facing stringent tests, and it can be expected
that WIMPs will be either be detected or the scenario will be so severely
constrained that it will have to be rethought. In this sense, we are on the
threshold of discovery. In this article, I will give a general overview of the
current status and future expectations for indirect searches of dark matter
(WIMP) particles.
