The landscape of QCD axion models
We review the landscape of QCD axion models. Theoretical constructions that extend the
window for the axion mass and couplings beyond conventional regions are highlighted and …

An even lighter QCD axion
A bstract We explore whether the axion which solves the strong CP problem can naturally be
much lighter than the canonical QCD axion. The\({Z} _ {\mathcal {N}}\) symmetry proposed …

Heavy axion opportunities at the DUNE near detector
While the QCD axion is often considered to be necessarily light (≲ eV), recent work has
opened a viable and interesting parameter space for heavy axions, which solve both the …
