The Too Visible QCD Axion
Luca Di Luzio, Michele Redi, Alessandro Strumia +2
The paper examines a GeV‑scale QCD axion model where the up‑quark mass arises from the QCD chiral condensate, identifies a structural problem that breaks isospin symmetry and disto…
A framework for missing-energy searches with anomalous light vectors
Luca Di Luzio, Marco Nardecchia, Stefano Scacco +1
We study light spin-1 gauge bosons coupled to electroweak-anomalous currents. For generic charge assignments, anomaly cancellation requires new fermions (anomalons) that are chiral…
RadioAxion results on the search for axion dark matter under Gran Sasso
Carlo Broggini, Giuseppe Di Carlo, Luca Di Luzio +2
We report first results from RadioAxion, an underground experiment searching for axion dark matter through periodic modulations of radioisotope decays. We monitor the decay of…
Weak nuclear decays deep-underground as a probe of axion dark matter
Jorge Alda, Carlo Broggini, Giuseppe Di Carlo +4
We investigate the time modulation of weak nuclear decays as a method to probe axion dark matter. To this end, we develop a theoretical framework to compute the -dependence of…
Probing a Light Scalar Boson with a few-MeV Proton Beam Deep Underground
Carlo Broggini, Giuseppe Di Carlo, Luca Di Luzio +2
We propose to investigate the production of a light scalar boson in low-energy proton-nucleus interactions using the 3.5 MV accelerator of the Bellotti Ion Beam Facility, loca…
The Chiral Lagrangian of CP-Violating Axion-Like Particles
Luca Di Luzio, Gabriele Levati, Paride Paradisi
We discuss the construction of the most general CP-violating chiral Lagrangian for an axion-like particle (ALP). Starting with an effective Lagrangian containing light quarks and g…
