The gravitational form factor of the pion and proton and the conformal anomaly

Autor: Corianò Claudio, Lionetti Stefano, Melle Dario, Tommasi Riccardo

Publikováno v: EPJ Web of Conferences, Vol 314, p 00030 (2024)

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 theory (CFT) description. These form factors are key to studying quark an

The 33311 Left-Right Bilepton Model

Autor: Corianò, Claudio, Frampton, Paul H., Melle, Dario

We discuss extension of the electroweak gauge group to $SU(3)_L \times SU(3)_R \times U(1)_{XL} \times U(1)_{XR}$. This adds new leptons to the familiar 331-model. The explanation for three light quark-lepton families remains but new particles are in

Conformal Backreaction, Chiral and Conformal Anomalies in the Early Universe

Autor: Corianò, Claudio, Lionetti, Stefano, Melle, Dario, Tommasi, Riccardo, Torcellini, Leonardo

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. This action, defined precisely in flat spacetime within ordinary quantum

The Gravitational Form Factors of Hadrons from CFT in Momentum Space and the Dilaton in Perturbative QCD

Autor: Corianò, Claudio, Lionetti, Stefano, Melle, Dario, Tommasi, Riccardo

We analyze the hard scattering amplitude of the gravitational form factors (GFFs) of hadrons at one-loop, in relation to their conformal field theory (CFT) description, within the framework of QCD factorization for hard exclusive processes at large m

The $SU(3)_C\times SU(3)_L\times U(1)_X$ (331) Model:Addressing the Fermion Families Problem within Horizontal Anomalies Cancellation

Autor: Corianò, Claudio, Melle, Dario

One of the most important and unanswered problems in particle physics is the origin of the three generations of quarks and leptons. The standard Model does not provide any hint regarding its sequential charge assignments, which remain a fundamental m

Axion-like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect

Autor: Corianò, Claudio, Cretì, Mario, Lionetti, Stefano, Melle, Dario, Tommasi, Riccardo

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, from early universe plasma to topological condensed matter. We outline
