Physical Reformulation of Multi-scale Evolution in Theoretical High-Energy Physics using Scalar QCD

Objectif

Quantum Chromodynamics (QCD) encompasses our most advanced knowledge of the strong interaction that governs the inner workings of protons, neutrons, and other hadrons. Its detailed understanding is imperative to interpret precision measurements at particle-collider experiments, which are essential to rigorously test the internal consistency of the Standard Model of Particle Physics. As QCD is an asymptotically free non-abelian gauge theory, perturbative QCD is the method of choice for theoretical predictions in high-energy particle scattering reactions involving the strong interaction.

The PROMETHEUS project will revolutionise the theoretical understanding and computational treatment of perturbative QCD by developing a fundamentally new approach to multi-scale evolution in particle reactions. Building on the semi-classical – scalar – limit, the project will derive universal structures of perturbative QCD without the need to perform any kinematical approximations that conventional methods require. For the first time, this approach will facilitate the derivation and implementation of a fully consistent framework for calculations in perturbative QCD, with a rigorous precision standard and well-defined connection to conventional resummation schemes and higher-order calculations.

The main outcomes of the project will be a fundamentally new understanding of perturbative QCD, particularly regarding its complex infrared structure, and a consistent framework for the calculation of high-precision theoretical predictions. This will systematically enable calculations at unprecedented precision and set new benchmarks for phenomenological studies in time for high-precision collider experiments, including the High-Luminosity Large Hadron Collider, the Electron-Ion Collider, and future lepton colliders.
