Colloque LPSC : The Strong Force: From Colliders to the Cosmos

by Andrea Shindler (RWTH Aachen University)

Thursday 9 Oct 2025, 10:00 → 11:00 Europe/Paris

The strong force binds quarks and gluons into protons and neutrons, making it fundamental to the structure of visible matter in the universe. Yet, its complexity makes quantitative predictions notoriously difficult. In this talk, I will discuss recent progress in solving the strong force on a space-time grid, an approach known as lattice QCD, and how the gradient flow, which smooths quantum fluctuations, has opened new opportunities on long-standing problems. I will show how these developments impact collider physics, providing first-principles input on the quark and gluon structure of the proton (parton distribution functions), and cosmology, predicting electric dipole moments as probes of new physics. Together, these efforts show how advances in theory and computation open new windows on fundamental questions about the universe.
