Findings

Mass arises dynamically from interactions in gauge theories.

High luminosity colliders will enable precise tests of chiral symmetry breaking.

Theoretical understanding of mass generation depends on detailed knowledge of particle interactions.

Abstract

This talk is in two parts both entitled mass production requires precision engineering. The first is about the dynamical generation of mass for matter particles in gauge theories. I will explain how the details of this depend on a precision knowledge of the interactions. The second is about tests of the mechanism of chiral symmetry breaking in QCD that the precision engineering of high luminosity colliders and particle detectors will shortly make possible. Since the latter topic has been described in Ref. 1, here I will just discuss the first: the production of mass from nothing.
