The Gravitational Form Factor of the Pion and Proton and the Conformal Anomaly
Claudio Corianò, Stefano Lionetti, Dario Melle +1
We analyze the hard scattering amplitude of gravitational form factors (GFFs) of hadrons within QCD factorization at large momentum transfers, focusing on their conformal field the…
Conformal Backreaction, Chiral and Conformal Anomalies in the Early Universe
Claudio Corianò, Stefano Lionetti, Dario Melle +2
The backreaction of a conformal matter sector and its associated conformal anomaly on gravity can be systematically studied using the formalism of the anomaly effective action. Thi…
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…
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…
Axion-like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect
Claudio Corianò, Mario Cretì, Stefano Lionetti +2
We discuss fundamental aspects of chiral anomaly-driven interactions in conformal field theory (CFT) in four spacetime dimensions. They find application in very general contexts, f…
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…
