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…
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…
Anomalies and Parity-Violating Interactions: From Conformal to Thermal Field Theory
Stefano Lionetti
Chiral and conformal anomalies are fundamental phenomena that span multiple disciplines, including high-energy physics, condensed matter theory and cosmology. These anomalies play…
A Dilaton Sum Rule for the Conformal Anomaly Form Factor in QCD at Order
Claudio Corianò, Stefano Lionetti, Dario Melle +1
We present an off-shell dispersive analysis of the graviton-gluon-gluon () vertex, extending previous investigations carried out in both QED and QCD. Within the framework of a…
Topological Sum Rules and Spectral Flows of Chiral and Gravitational Axion-like Interactions
Claudio Corianò, Stefano Lionetti, Dario Melle
We examine the structure of off-shell effective actions arising from chiral and gravitational anomalies, focusing on the (axial-vector/vector/vector) and (axial-v…
