On the fermionic couplings of axionic dark matter
Christopher Smith
In the non-relativistic limit, two types of dark matter axion interactions with fermions are thought to dominate: one is induced by the spatial gradient of the axion field and call…
Axion-like ALPs
Fernando Arias-Aragón, Jérémie Quevillon, Christopher Smith
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. In this…
Leptoquarks, axions and the unification of B, L, and Peccei-Quinn symmetries
Fernando Arias-Aragón, Christopher Smith
In this paper, axion models supplemented by leptoquarks and diquarks are systematically analyzed. Turning on some couplings to and among these latter states permits to unify the Pe…
Axion Effective Action
Jérémie Quevillon, Christopher Smith, Pham Ngoc Hoa Vuong
In this paper, we discuss the construction of Effective Field Theories (EFTs) in which a chiral fermion, charged under both gauge and global symmetries, is integrated out. Inspired…
Variations on the SU(5) axion
Jérémie Quevillon, Christopher Smith
The simultaneous embeddings of an axion state and a seesaw mechanism within the SU(5) Grand Unification Theory, both minimal and flipped, are systematically studied. It is shown th…
Baryon and lepton number intricacies in axion models
Jérémie Quevillon, Christopher Smith
Because the Peccei-Quinn (PQ) symmetry has to be anomalous to solve the strong CP puzzle, some colored and chiral fermions have to transform non-trivially under this symmetry. But…
