Nonperturbative Quantum Field Theory on the Lattice

Abstract

These lectures provide an introduction to lattice methods for nonperturbative studies of quantum field theories, with an emphasis on Quantum Chromodynamics. Lecture 1 (Ch. 2): gauge field basics Lecture 2 (Ch. 3): Abelian duality with a lattice regulator (Ch. 4): simple lattice intuition Lecture 3 (Ch. 5): standard methods (and results) for hadron spectroscopy Lecture 4 (Ch. 6): bare actions and physics Lecture 5 (Ch. 7): two case studies, mass of the glueball and ${\alpha }_s(M_Z)$
