"Lattice QCD -- and Beyond"
Quantum chromodynamics (QCD)
is the fundamental theory of the strong nuclear
force. The formulation of QCD on a space-time
lattice has helped physicists gain a deeper
understanding of the theory through high-performance
computing. Although numerical investigations
of lattice QCD have been underway for decades,
in recent years this work has reached an unprecedented
level of maturity. We have also begun to use
lattice methods to study more exotic theories
beyond QCD, including theories that attempt
to explain the origin of elementary particles'
masses. In this talk I will present an overview
of lattice QCD -- and beyond -- for computational
scientists. I will discuss the questions we
aim to answer, the methods we use, the challenges
we face and the new opportunities we look forward
to in the future.
