Implications of protecting the QCD axion in the dual description
Journal of High Energy Physics, 2023 The QCD axion can be formulated in a dual description as a massive 2-form field. In this picture, the QCD axion quality problem translates into the question if there are additional 3-forms coupled to the axion other than the QCD 3-form that emerges at ...

Axion results: what is new? [PDF]
, 2006 The PVLAS collaboration has obtained results that may be interpreted in terms of a light axion-like particle, while the CAST collaboration has not found any signal of such particles.

Flavor probes of axion-like particles
Journal of High Energy Physics, 2022 Abstract 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 ALP with flavor-changing couplings, and present a comprehensive analysis of quark and lepton flavor-changing observables within a general ALP effective ...

The minimal axion minimal linear $$\sigma $$ σ model
European Physical Journal C: Particles and Fields, 2018 The minimal SO(5) / SO(4) linear $$\sigma $$ σ model is extended including an additional complex scalar field, singlet under the global SO(5) and the Standard Model gauge symmetries. The presence of this scalar field creates the conditions to generate an

Compatibility of CAST search with axion-like interpretation of PVLAS results [PDF]
, 2006 The PVLAS collaboration has results that may be interpreted in terms of a light axion-like particle, while the CAST collaboration has not found any signal of such particles. We propose a particle physics model with paraphotons and with a low energy scale

Some properties of multi-component axion dark matter
Physics Letters BWe introduce a mechanism for multi-component dark matter (DM) that originates from axion mixing and present some of its defining properties. In this context, multi-component DM implies that the cold DM is composed of the QCD axion and many ultra-light ...

Axion dark matter detection by superconducting resonant frequency conversion
Journal of High Energy Physics, 2020 We propose an approach to search for axion dark matter with a specially designed superconducting radio frequency cavity, targeting axions with masses m a ≲ 10 −6 eV. Our approach exploits axion-induced transitions between nearly degenerate resonant modes

No light shining through a wall : new results from a photoregeneration experiment
, 2007 Recently, axion-like particle search has received renewed interest. In particular, several groups have started ``light shining through a wall'' experiments based on magnetic field and laser both continuous, which is very demanding in terms of detector ...

Mississippi State Axion Search: A Light Shining though a Wall ALP Search
, 2014 The elegant solutions to the strong CP problem predict the existence of a particle called axion. Thus, the search for axion like particles (ALP) has been an ongoing endeavor.

Cornering the axion-like particle explanation of quasar polarisations [PDF]
, 2012 In a series of paper, it has been shown that the distribution of polarisation position angles for visible light from quasars is not random in extremely large regions of the sky.
