The QCD Trace Anomaly in Pion Gravitational Form Factors with Sudakov Resummation
Claudio Corianò, Dario Melle, Leonardo Torcellini
We discuss the pion gravitational form factors at intermediate and large spacelike momentum transfer in a perturbative-QCD factorization framework. The short-distance kernel is sup…
Numerical polology: towards next-generation model-building for cosmology
Will Barker, Will Handley, Michael Hobson +4
The dark sector need not be restricted to simple field content. Indeed, simple bosonic configurations, such as scalar-tensor or dark photon models, contrast with the much richer pi…
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…
Consistency Conditions for Astrons
Claudio Corianò, Paul H. Frampton, Leonardo Torcellini
We reassess the consistency conditions for a hypothetical population of primordial, electrically charged compact objects, here called astrons. This paper formulates astrons not as…
Astrons: Reissner-Nordström Primordial Naked Singularities
Claudio Corianò, Paul H. Frampton, Leonardo Torcellini
We summarize a set of constraints on a proposed population of primordial, ultra-massive, electrically charged compact objects, which we call astrons. The analysis combines charge g…
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…
