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…
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…
Heavy Quark Decays in the Bilepton Model
Gennaro Corcella, Claudio Corianò, Dario Melle +1
Given the current absence of new physics signals at the LHC, it is increasingly important to investigate alternative scenarios beyond those commonly explored. In this work, we stud…
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…
