An even lighter QCD axion
Luca Di Luzio, Belen Gavela, Pablo Quilez +1
We explore whether the axion which solves the strong CP problem can naturally be much lighter than the canonical QCD axion. The symmetry proposed by Hook, with $\ma…

Comments on gauge anomalies at dimension-six in the Standard Model Effective Field Theory
Quentin Bonnefoy, Luca Di Luzio, Christophe Grojean +2
We study whether higher-dimensional operators in effective field theories, in particular in the Standard Model Effective Field Theory (SMEFT), can source gauge anomalies via the mo…

The Anomalous Case of Axion EFTs and Massive Chiral Gauge Fields
Quentin Bonnefoy, Luca Di Luzio, Christophe Grojean +2
We study axion effective field theories (EFTs), with a focus on axion couplings to massive chiral gauge fields. We investigate the EFT interactions that participate in processes wi…
