We carry out a systematic study of a broad class of UV completions of the Standard Model containing vector-like fermions and a complex scalar responsible for spontaneous PQ-symmetry breaking and the emergence of an axion-like particle (ALP). We classify the viable models and match them onto both SMEFT and ALP effective theories, deriving the corresponding low-energy descriptions for each case....

Axion-like particle (ALP) effective field theories (EFTs) provide a powerful, UV-agnostic framework for studying ALP phenomenology. Phenomenological analyses within this framework typically assume that the ALP mass lies well below the decay constant, i.e. $m_a << f_a$, following standard EFT intuition. In this poster, motivated by the analogous situation in chiral perturbation theory - where...
