abstract
We study the effects that a non zero strong-CP-violating parameter theta would have on the deuteron and diproton binding energies and on the triple-alpha process. Both these systems exhibit fine tuning, so it is plausible that a small change in the nuclear force would produce catastrophic consequences. Such a nuclear force is here understood in the framework of an effective Lagrangian for pions and nucleons, and the strength of the interaction varies with theta. We find that the effects are not too dramatic.

Model-independent reinterpretation of Belle II B+ → K+ νν̄ data using public kinematic mapping yields a factor-of-nine improvement on the limit for B+ → K+ a and constrains the axion's b-s flavor-changing coupling.
LISA forecasts for quadratically coupled ultralight dark matter show competitive or superior sensitivity to terrestrial and astrophysical probes in selected mass windows, free of screening.
A framework is developed to predict axion-induced time modulations in weak nuclear decays, used to derive constraints on the axion decay constant from reanalyzed Gran Sasso data on 40K and 137Cs and to propose future sensitivity to higher masses.
Astrophysical S-factor data constrain variations in the electromagnetic fine-structure constant to |δ α/α| ≤ 0.0002 in radiative alpha capture on carbon-12.
Review classifies QCD axion models extending the standard mass-coupling window and updates bounds from cosmology, astrophysics, and experiments.
