Axion production via trapped misalignment from Peccei-Quinn symmetry breaking
Luca Di Luzio, Philip Sørensen
The Peccei-Quinn (PQ) symmetry does not need to be exact, and even a tiny source of PQ breaking not aligned with the QCD anomaly might have significant phenomenological implication…
Radiative Quarkonium decays into an Invisible ALP
Luca Di Luzio, Alfredo Walter Mario Guerrera, Xavier Ponce Díaz +1
In this talk the ALP production from radiative quarkonium decays is presented. To this purpose, the relevant cross-section is computed from a effective Lagrangian containing…
Axion-Like Particles in Radiative Quarkonia Decays
Luca Di Luzio, Alfredo Walter Mario Guerrera, Xavier Ponce Díaz +1
Radiative quarkonia decays offer an ideal setting for probing Axion-Like Particle (ALP) interactions. This paper provides a comprehensive review of ALP production mechanisms throug…
CP-Violating Axions: A Theory Review
Luca Di Luzio, Hector Gisbert, Gabriele Levati +2
We review the physics case for CP-violating axions. In the first part, we focus on the Quantum Chromodynamics (QCD) axion and argue that new sources of CP violation beyond QCD misa…
Flavour constraints on light spin-1 bosons within a chiral Lagrangian approach
Luca Di Luzio, Gabriele Levati, Paride Paradisi +1
We discuss the construction of the chiral Lagrangian for a light spin-1 boson, here denoted as , featuring both vector and axial-vector couplings to light quarks. Focusi…
UV-IR interplay in axion flavour violation
Luca Di Luzio, Alfredo Walter Mario Guerrera, Xavier Ponce Díaz +1
Flavour-violating axions appear in models where the Peccei-Quinn(PQ) charges are generation non-universal. Consequently, this charge arrangement will also generate flavour violatio…
