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…

Semiclassical Lensing and Radiative Lens Equations
Claudio Corianò, Mario Cretì, Leonardo Torcellini
We analyze lensing of photons and neutrinos in a gravitational field, proposing a method to include radiative effects in classical lens equations. The study uses Schwarzschild and…
