Searching for Axion-like Particles with Active Galac- tic Nuclei
An Axion-Like Particle (ALP) is any scalar or pseudo-scalar field which couples to the kinetic terms of the photon. The pseudo scalar coupling to photons is identical to that of the axion; L ⊃ φ 4M ǫμνλρFF, and a scalar field couples through the Lagrangian term; L ⊃ φ 4MFμνF μν . The presence of contact interactions between ALPs and photons means that ALPs affect the propagation of photons thro...
متن کاملSearching for the Axion
This talk focuses on the search for the axion, a hypothetical elementary particle which historically appreared in a compelling solution to the Strong-CP problem in QCD. Subsequently, the axion was recognized to be a good Cold Dark Matter candidate. Although dark matter axions have only feeble couplings to matter and radiation, extremely sensitive searches are underway around the world. In this ...
متن کاملThe Gammev Suite of Experimental Searches for Axion-like Particles
We report on the design and results of the GammeV search for axion-like particles and for chameleon particles. We also discuss plans for an improved experiment to search for chameleon particles, one which is sensitive to both cosmological and power-law chameleon models. Plans for an improved axion-like particle search using coupled resonant cavities are also presented. This experiment will be m...
متن کاملEvading Astrophysical Constraints on Axion-Like Particles
Stellar energy loss arguments lead to strong constraints on the coupling φγγ of a light axion-like particle to two photons. Helioscopes, like CAST, are able to put competitive bounds. The PVLAS experiment has recently observed a rotation of the polarization of a laser propagating in a magnetic field that can be interpreted as the effect of a quite strong φγγ coupling. We present scenarios where...
متن کاملAxion Searches with Helioscopes and astrophysical signatures for axion(-like) particles
Axions should be produced copiously in Stars such as the Sun. The first part of the article reviews the capabilities and performance of axion helioscopes. The mechanism they rely on is described and the achieved experimental results for the interaction of solar axions and axion-like particles with matter are given. The second part is observationally driven. New results obtained with Monte Carlo...
