From chiral to conformal anomalies: a double copy perspective for CFT correlators
Claudio Corianò, Stefano Lionetti
We uncover a double-copy relation between chiral and conformal anomalies in four-dimensional conformal field theory. We show that this relation extends from local anomaly structure…
The Pion Gravitational Form Factors and the Trace Anomaly in QCD Factorization
Claudio Corianò, Hsiang-nan Li, Dario Melle
We study the pion gravitational form factor in QCD factorization, focusing on the trace-anomaly component generated by the non-Abelian \(TJJ\) vertex. The calculation combines a Su…
The Gravitational Form Factor of the Pion in Perturbative QCD with a Dilaton Interaction
Claudio Corianò, Hsiang-nan Li, Dario Melle +1
We investigate the pion gravitational form factors (GFFs) at intermediate and large momentum transfer within the framework of QCD factorization. Our analysis centers on the non-Abe…
The Case for Astrons
Claudio Corianò, Paul H. Frampton, Leonardo Torcellini
We examine a proposed population of primordial, electrically charged compact objects, which we call astrons, with fiducial parameters \(M_A\sim10^{12}M_\odot\), \(Q_A\sim4\times10^…
Gauging Axionic Symmetries and Dark Matter: In memory of George Lazarides
Claudio Corianò
These notes are written for a memorial Session dedicated to George Lazarides. They revisit a joint work on the cosmology of a gauged axion and place it in a broader line of ideas c…
Anomaly-mediated Scalar Gravitational Interactions and the Coupling of Conformal Sectors
Claudio Corianò, Stefano Lionetti, Dario Melle +1
We investigate the anomaly-induced activation of a gauge-invariant scalar degree of freedom in General Relativity, the conformalon mode, directly at the level of \(2\to2\) scatteri…
