Overview

Lecture notes discuss effective field theory insights on strong CP and QCD axion physics, highlighting the Peccei-Quinn mechanism.

Key Points

  • This work aims to provide a comprehensive introduction to the strong CP problem and QCD axion physics through effective field theory.
  • Review of chiral effective field theory (EFT) of QCD
  • Analysis of theta-dependent potential and related structures
  • Extraction of CP-odd mesonic and baryonic amplitudes
  • Discussion of the Veneziano–Yankielowicz effective Lagrangian in N=1 supersymmetric Yang-Mills theory
  • Comparison with no strong CP claim in the context of EFT.
  • Establishment of a theta-dependent potential from chiral EFT
  • Clarification of the role of topological susceptibility in hadronic observables
  • Demonstration of the Peccei-Quinn mechanism and its implications
  • Insights into axion potential and mass derived from the effective framework
