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…
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…
Quantum Anomalies and Parity-odd CFT Correlators for Chiral States of Matter
Claudio Corianó, Stefano Lionetti
Chiral currents influence the parity-odd sector of CFT correlators in momentum space, playing a crucial role in the evolution of the quark-gluon plasma in the early universe. We de…
CFT Constraints on Parity-odd Interactions with Axions and Dilatons
Claudio Corianó, Stefano Lionetti
We illustrate how the conformal Ward identities (CWIs) in momentum space completely determine the structure of a parity-odd 3-point correlator involving currents, energy momentum t…
Nonlocal Gravity, Dark Energy and Conformal Symmetry: Testing the Hierarchies of Anomaly-Induced Actions
Claudio Corianò, Stefano Lionetti, Matteo Maria Maglio +1
Conformal back-reaction generates cosmological models where the trace anomaly reflects the breaking of Weyl invariance. Analyzing these actions yields a dynamic approach to dark en…
The Gravitational Chiral Anomaly at Finite Temperature and Density
Claudio Corianò, Mario Cretì, Stefano Lionetti +1
We investigate the gravitational anomaly vertex (graviton - graviton - axial current) under conditions of finite density and temperature. Through a direct an…
Parity-Violating CFT and the Gravitational Chiral Anomaly
Claudio Corianò, Stefano Lionetti, Matteo Maria Maglio
We illustrate how the Conformal Ward Identities (CWI) and the gravitational chiral anomaly completely determine the structure of the (graviton-graviton-chi…
CFT Correlators and CP-Violating Trace Anomalies
Claudio Corianò, Stefano Lionetti, Matteo Maria Maglio
We analyze the parity-odd correlators , , and in momentum space, constrain…
Einstein Gauss-Bonnet Gravity without a Dilaton
Claudio Corianò, Mario Cretì, Stefano Lionetti +2
A nonlocal version of Einstein-Gauss Bonnet (EGB) gravity can be generated by a procedure that follows closely the steps of the derivation of the conformal anomaly effective action…
Parity-Odd 3-Point Functions from CFT in Momentum Space and the Chiral Anomaly
Claudio Corianò, Stefano Lionetti, Matteo Maria Maglio
We illustrate how the Conformal Ward Identities (CWI) in momentum space for parity-odd correlators determine the structure of a chiral anomaly interaction, taking the example of th…
Three-Wave and Four-Wave Interactions in the Einstein Gauss-Bonnet (EGB) and Lovelock Theories
Claudio Corianò, Mario Cretì, Stefano Lionetti +1
We derive the conformal constraints satisfied by classical vertices of a (Einstein) Gauss-Bonnet theory around flat space, in general dimensions and at (4d EGB). In EGB…
Asymptotic symmetries and soft theorems in higher-dimensional gravity
Stefano Lionetti
Soft theorems can be recast as Ward identities of asymptotic symmetries. We review such relation for the leading and subleading soft graviton theorems in arbitrary even dimensions.…
Dimensional Regularization of Topological Terms in Dilaton Gravity
Claudio Corianò, Mario Cretì, Stefano Lionetti +2
The possibility of evading Lovelock's theorem at , via a singular redefinition of the dimensionless coupling of the Gauss-Bonnet term, has been extensively discussed in the co…
Asymptotic symmetries and subleading soft graviton theorem in higher dimensions
Dimitri Colferai, Stefano Lionetti
We investigate the relation between the subleading soft graviton theorem and asymptotic symmetries in gravity in even dimensions higher than four. After rewriting the subl…
