TL;DR: Experimental constraints on ALPs with a single dominant lepton-flavor-violating coupling are discussed and allowing for one or more such couplings offers qualitatively new ways to explain the anomalies related to the magnetic moments of the muon or the electron.

TL;DR: In this article, the authors studied the evolution of axion-like particle couplings from the new-physics scale to energies at and below the scale of electroweak symmetry breaking.

TL;DR: In this article , the authors summarize the relevant phenomenological models and the status of the searches in a comprehensive list of kaon and hyperon decay channels and identify new search strategies for under-explored signatures, and demonstrate that improved sensitivities from current and next-generation experiments could lead to a qualitative leap in the exploration of light dark sectors.

TL;DR: In this paper, the authors present a consistent implementation of weak decays involving an axion or axion-like particle in the context of an effective chiral Lagrangian, and derive model-independent results for the decays with axion couplings and mass.

TL;DR: In this paper, the authors investigated the phenomenology of an axion-like particle with flavor-changing couplings, and presented a comprehensive analysis of quark and lepton flavor changing observables within a general ALP effective field theory.
