Nonperturbative Quantum Field Theory on the Lattice
T. DeGrand
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 αs(MZ)
