Experimental Searches for the Axion and Axion-Like Particles 2015 Access copy available to the general public Unrestricted Four decades after its prediction, the axion remains the most compelling solution to the strong-CP problem and a well-motivated dark matter candidate, inspiring a host of elegant and ultrasensitive experiments based on axion-photon mixing. This article reviews the experimental situation on several fronts. The microwave cavity experiment is making excellent progress in the search for dark matter axions in the µeV range and may plausibly be extended up to 100 µeV. Within the past several years, however, researchers have realized that axions are pervasive throughout string theories, but with masses that fall naturally in the neV range, for which an NMR-based search is under development. Both searches for axions emitted from the Sun's burning core and purely laboratory experiments based on photon regeneration have recently made great progress, with ambitious projects proposed for the coming decade. Each of these campaigns has pushed the state of the art in technology, enabling large gains in sensitivity and mass reach. Furthermore, each modality has been exploited in order to search for more generalized axion-like particles, which we also discuss in this review. We are hopeful, even optimistic, that the next review of the subject will concern the discovery of the axion, its properties, and its exploitation as a probe of early universe cosmology and structure formation. info:eu-repo/grantAgreement/EUR/ERC-PHY-1067242 info:eu-repo/grantAgreement/EUR/ERC-PHY-1306729 info:eu-repo/grantAgreement/EUR/ERC-PHY-1316706 info:eu-repo/grantAgreement/EC/FP7/240054/EU/Novel Developments in Time Projection Chambers (TPCs) for Rare Event Searches in Underground Astroparticle EXperiments/TREX info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 7.5 2015 PHYSICS, PARTICLES & FIELDS 3 / 28 = 0.107 2015 Q1 T1 PHYSICS, NUCLEAR 2 / 21 = 0.095 2015 Q1 T1 5.823 2015 Nuclear and High Energy Physics 2015 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/submittedVersion Irastorza, I.G.
