Searching for the Axion
نویسنده
چکیده
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 talk we review the state of experiments searching for the axion through its coupling to photons, with emphasis on experiments that look for axions that could make up dark matter.

Hunting for Chameleons in ALP searches
We discuss some recent developments in chameleon models presented at the Fourth Patras workshop on Axions, WIMPs and WISPs. In particular we discuss the possibility of searching for chameleons in axion-like particle searches performed in the laboratory. Such chameleons may couple to both photons and matter with different coupling strengths. We discuss the exciting possibility of searching for t...
متن کاملProposal for axion dark matter detection using an LC circuit.
We show that dark matter axions cause an oscillating electric current to flow along magnetic field lines. The oscillating current induced in a strong magnetic field B0 produces a small magnetic field Ba. We propose to amplify and detect Ba using a cooled LC circuit and a very sensitive magnetometer. This appears to be a suitable approach to searching for axion dark matter in the 10(-7) to 10(-9...
متن کاملThe Need for Purely Laboratory-Based Axion-Like Particle Searches
Abstract The PVLAS signal has led to the proposal of many experiments searching for light bosons coupled to photons. The coupling strength probed by these near future searches is, however, far from the allowed region, if astrophysical bounds apply. But the environmental conditions for the production of axion-like particles in stars are very different from those present in laboratories. We consi...
متن کاملSearching 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 axions and ALPs from string theory
We review searches for closed string axions and axion-like particles (ALPs) in IIB string flux compactifications. For natural values of the background fluxes and TeV scale gravitino mass, the moduli stabilisation mechanism of the LARGE Volume Scenario predicts the existence of a QCD axion candidate with intermediate scale decay constant, fa ∼ 10 9÷12 GeV, associated with the small cycles wrappe...
