In the late 1970s, the axion was proposed as a solution to the strong CP problem, ie, the
puzzle why the strong interactions conserve parity P and the product CP of charge …

Axions and other very light axion-like particles appear in many extensions of the Standard
Model, and are leading candidates to compose part or all of the missing matter of the …

A bstract Axions and axion-like particles (ALPs) are well-motivated low-energy relics of high-
energy extensions of the Standard Model (SM). We investigate the phenomenology of an …

During 2003--2015, the CERN Axion Solar Telescope (CAST) has searched for $
a\to\gamma $ conversion in the 9 T magnetic field of a refurbished LHC test magnet that can …

A bstract Axion-like particles (ALPs), which are gauge-singlets under the Standard Model
(SM), appear in many well-motivated extensions of the SM. Describing the interactions of …

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 …

Axion-like particles (ALPs) are pseudo Nambu–Goldstone bosons of spontaneously broken
global symmetries in high-energy extensions of the Standard Model (SM). This makes them …

Very weakly interacting slim particles (WISPs), such as axion-like particles (ALPs) or hidden
photons (HPs), may be non-thermally produced via the misalignment mechanism in the …

Axions can be copiously produced in localized regions of neutron star magnetospheres
where the ambient plasma is unable to efficiently screen the induced electric field. As these …
