Topological Axi-Higgs Dynamics in Anomalous Portals
Claudio Corianò, Stefano Lionetti
We develop an effective axi-Higgs model with one Standard Model Higgs doublet, one charged hidden Higgs and an anomalous Abelian vector portal. Extending previous Higgs--Stueckelbe…
The QCD Trace Anomaly in Pion Gravitational Form Factors with Sudakov Resummation
Claudio Corianò, Dario Melle, Leonardo Torcellini
We discuss the pion gravitational form factors at intermediate and large spacelike momentum transfer in a perturbative-QCD factorization framework. The short-distance kernel is sup…
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…
Consistency Conditions for Astrons
Claudio Corianò, Paul H. Frampton, Leonardo Torcellini
We reassess the consistency conditions for a hypothetical population of primordial, electrically charged compact objects, here called astrons. This paper formulates astrons not as…
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…
Dilaton Sum Rules of Gravitational Form Factors in QCD at Order
Claudio Corianò, Stefano Lionetti, Dario Melle +1
We formulate a partonic description of hadronic gravitational form factors within QCD, focusing on the three-point function of the energy-momentum tensor and two gluon currents. De…
