Standard Model (SM) of particle physics has achieved enormous success in describing the interactions among the known fundamental constituents of nature, yet it fails to describe phenomena for which there is very strong experimental evidence, such as the existence of dark matter, and which point to the existence of new physics not included in that model; beyond its existence, experimental data, however, have not provided clear indications as to the nature of that new physics. The effective field theory (EFT) approach, the subject of this review, is designed for this type of situations; it provides a consistent and unbiased framework within which to study new physics effects whose existence is expected but whose detailed nature is known very imperfectly. We will provide a description of this approach together with a discussion of some of its basic theoretical aspects. We then consider applications to high-energy phenomenology and conclude with a discussion of the application of EFT techniques to the study of dark matter physics and it possible interactions with the SM. In several of the applications we also briefly discuss specific models that are ultraviolet complete and may realize the effects described by the EFT.

Reviving WIMP dark matter with temperature-dependent couplings
Temperature-dependent DM couplings mediated by a scalar field's VEV that drops after a first-order phase transition allow sufficient early-universe annihilations for the observed relic density while evading current di...

Semi-visible higgs decay as a probe for new invisible particles
At the HL-LHC, semi-visible Higgs decays can probe dark-SMEFT couplings to invisible scalars or fermions below 50 GeV, with the best reach for Yukawa-type operators, while invisible Z decays and unitarity constrain de...

From WIMP to FIMP during reheating: collider vs non-collider probes for p-wave annihilation
Collider experiments can strongly constrain p-wave-suppressed derivative operators and thereby limit reheating temperature, DM mass, and interaction scale needed to match observed DM abundance during reheating.

Constraining Effective Field Theories for dark matter candidates annihilating into gamma-ray lines with CTAO
Using CTAO projected line sensitivity, the paper forecasts lower bounds on effective dark matter interaction scales above 10 TeV for TeV mass dark matter, with direct detection dominating the fermionic dipole operator.
