The QCD Axion - Lecture 1

International Centre for Theoretical Sciences via YouTube

Overview

Explore the intricacies of the QCD Axion in this comprehensive lecture by David Marsh from the International Centre for Theoretical Sciences. Delve into topics such as the Strong-CP problem, spontaneous symmetry breaking, and the chiral anomaly. Learn about axion ingredients, the PQ Lagrangian, and axion-fermion coupling. Examine the QCD axion potential, ChPT and axion mass, and lattice QCD applications. Discover various QCD axion models and constraints in this 1 hour 29 minute presentation, part of a program on less-traveled paths of dark matter focusing on axions and primordial black holes.
