Axions and ALPs: a very short introduction [PDF]
, 2017 The QCD axion was originally predicted as a dynamical solution to the strong CP problem. Axion like particles (ALPs) are also a generic prediction of many high energy physics models including string theory.

Search for Electric Dipole Moments and Axions/ALPS with Polarized Beams in Storage RIngs
Proceedings of 20th International Workshop on Polarized Source, Targets, and Polarimetry — PoS(PSTP2024)The research investigates two main questions in particle physics and cosmology: the fate of antimatter after the Big Bang and the nature of Dark Matter (DM).

Cosmological constraints on thermal relic axions and axion-like particles [PDF]
, 2011 Cosmological precision data can be used to set very strict constraints on Axions and Axion-like particles (ALPs) produced thermally in the big bang. We briefly review the known bounds and propose two new constraints for Axions and ALPs decaying in the ...

A comprehensive study of ALPs from B-decays
Journal of High Energy PhysicsWe present a comprehensive study of axion-like particles (ALPs) through flavor changing neutral current processes, such as B → Ka followed by a → hadronic, γγ, μ + μ − channels. Our generic framework encompasses different ultraviolet scenarios similar to

Mississippi State Axion Search: A Light Shining though a Wall ALP Search
arXiv: Instrumentation and Detectors, 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.

Audible axions with a booster: Stochastic gravitational waves from rotating ALPs [PDF]
SciPost Physics, 2022 Gravitational waves provide a novel way to probe axions or axion-like particles coupled to a dark photon field, even in the absence of couplings to Standard Model particles. In the conventional misalignment mechanism, the generation of an observable stochastic gravitational wave background, however, requires large axion decay constants.

The ALPs from the top: searching for long lived axion-like particles from exotic top decays [PDF]
Journal of High Energy Physics, 2022 Abstract We propose a search for long lived axion-like particles (ALPs) in exotic top decays. Flavour-violating ALPs appear as low energy effective theories for various new physics scenarios such as t-channel dark sectors or Froggatt-Nielsen models. In this case the top quark may decay to an ALP and an up- or charm-quark.

Intermediate Scale Accidental Axion and ALPs
, 2014 We discuss the problem of constructing models containing an axion and axion-like particles, motivated by astrophysical observations, with decay constants at the intermediate scale ranging from $10^9$GeV to $10^{13}$GeV. We present examples in which the axion and axion-like particles arise accidentally as pseudo Nambu-Goldstone bosons of automatic ...
