The low-energy effective theory of axions and ALPs [PDF]
Journal of High Energy Physics, 2021 Abstract Axions and axion-like particles (ALPs) are well-motivated low-energy relics of high-energy extensions of the Standard Model, which interact with the known particles through higher-dimensional operators suppressed by the mass scale Λ of the new-physics sector.

Supernova Muons: New Constraints on Z′ Bosons, Axions and ALPs [PDF]
Journal of High Energy Physics, 2021 Abstract New light particles produced in supernovae can lead to additional energy loss and a consequent deficit in neutrino production in conflict with the neutrinos observed from Supernova 1987A (SN1987A). Contrary to the majority of previous SN1987A studies, we examine the impact of Z′ bosons, axions, and axion-like particles ...

Searching for axions and ALPs from string theory [PDF]
Journal of Physics: Conference Series, 2014 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, f_a ~ 10^9 ...

Aspects of Axions and ALPs Phenomenology [PDF]
Journal of Physics: Conference Series, 2023 Abstract The physics of axions and axion-like particles (ALPs) is enjoying an incredibly productive period, with many new experimental proposals, theoretical idea, and original astrophysical and cosmological arguments which help the search effort.

The quest for an intermediate-scale accidental axion and further ALPs [PDF]
Journal of High Energy Physics, 2014 La détection récente de l'expérience du polarimètre de fond cosmologique à micro-ondes BICEP2 des fluctuations des tenseurs dans le spectre de puissance en mode B exclut fondamentalement tous les modèles d'axions plausibles où sa constante de désintégration est supérieure à $ 10^{13}$ GeV.

Journal of High Energy Physics, 2023 The Effective Field Theory (EFT) Lagrangian for a generic axion-like particle (ALP) has many free parameters, and leaves quite some freedom for the expected phenomenology.

Alternative dark matter candidates: axions and ALPs [PDF]
Proceedings of Neutrino Oscillation Workshop — PoS(NOW2018), 2019 The QCD axion and particles with similar properties (axion-like particles or ALPs) are excellent candidates to be the cold dark matter of the Universe. They are extremely different to the standard WIMP, however. In this talk I presented and highlighted the mostly shocking aspects of axion dark matter, the prospects for its discovery and the recent ...

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 ...

Search for Electric Dipole Moments and Axions/ALPS with Polarized Beams in Storage RIngs [PDF]
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). It focuses on studying Electric Dipole Moments (EDMs) in particles like protons and deuterons using polarized particle beams in a storage ring.
