The existence of a new kind of matter — dark matter (DM) — is by now well-established from astronomical and cosmological observations. In
broad terms, a dark matter particle (or particles) should be massive, neutral, weakly interacting with standard model particles, and stable in
cosmological scales in order to be able to explain the previously mentioned observations. There is no standard model particle with these
properties, but there is considerable freedom on the definition of new physics models that could contain a viable DM candidate. Some of those
models are, in principle, amenable to collider searches; we will review the modus operandi of such a search, and proceed to showcase some
results of searches for dark matter with the CMS experiment. We will also discuss the interpretation of the results in the context of several
different benchmark models.
