Lattice gauge theory: A retrospective
Michael Creutz
TL;DR
This paper reviews the historical development and successes of lattice gauge theory as a non-perturbative approach to understanding strong interactions, highlighting its achievements and future challenges.
Contribution
It provides a retrospective overview of lattice gauge theory, emphasizing its role in demonstrating quark confinement and deriving properties of strong interactions from first principles.
Findings
Confirmed quark confinement through lattice simulations
Derived key properties of strong interactions non-perturbatively
Discussed future challenges for lattice gauge theory
Abstract
I discuss some of the historical circumstances that drove us to use the lattice as a non-perturbative regulator. This approach has had immense success, convincingly demonstrating quark confinement and obtaining crucial properties of the strong interactions from first principles. I wrap up with some challenges for the future.
