QCD’s IR and UV limits

10:30AM, 3 Mar 2025

Dr Andrea Guerrieri explores QCD in two distinct regimes to illustrate its pivotal role in shaping our understanding of fundamental physics.

Quantum Chromodynamics has been a profound source of inspiration for theoretical physicists, driving the development of key concepts such as string theory, effective field theories, instantons, anomalies, and lattice gauge theories. In this four-part lecture series, Dr Guerrieri will explore two distinct regimes of Quantum Chromodynamics—its infrared and ultraviolet limits—and the theoretical tools used to study them.

In the infrared regime, where perturbative techniques break down, Effective Field Theories provide a powerful framework. Here, Dr Guerrieri will introduce the pion EFT as a tool to study non-linearly realized symmetries and soft theorems. In the ultraviolet regime, where Quantum Chromodynamics becomes amenable to perturbative analysis, he will discuss the Operator Product Expansion and renormalization group equations, focusing on their application to deep inelastic scattering, a cornerstone in the discovery of quarks and gluons.
