Indirect detection of dark matter is a method of searching for dark matter that focuses on looking for the products of dark matter interactions (particularly Standard Model particles) rather than the dark matter itself. Contrastingly, direct detection of dark matter looks for interactions of dark matter directly with atoms. There are experiments aiming to produce dark matter particles using colliders. Indirect searches use various methods to detect the expected annihilation cross sections for weakly interacting massive particles (WIMPs). It is generally assumed that dark matter is stable (or has a lifetime long enough to appear stable), that dark matter interacts with Standard Model particles, that there is no production of dark matter post-freeze-out, and that the universe is currently ma

| - Indirect detection of dark matter is a method of searching for dark matter that focuses on looking for the products of dark matter interactions (particularly Standard Model particles) rather than the dark matter itself. Contrastingly, direct detection of dark matter looks for interactions of dark matter directly with atoms. There are experiments aiming to produce dark matter particles using colliders. Indirect searches use various methods to detect the expected annihilation cross sections for weakly interacting massive particles (WIMPs). It is generally assumed that dark matter is stable (or has a lifetime long enough to appear stable), that dark matter interacts with Standard Model particles, that there is no production of dark matter post-freeze-out, and that the universe is currently matter-dominated, while the early universe was radiation-dominated. Searches for the products of dark matter interactions are profitable because there is an extensive amount of dark matter present in the universe, and presumably, a lot of dark matter interactions and products of those interactions (which are the focus of indirect detection searches); and many currently operational telescopes can be used to search for these products. Indirect searches help to constrain the annihilation cross section the lifetime of dark matter , as well as the annihilation rate. (en)
