LatticeQCD: Lattice Quantum Chromodynamics for Exascale

Principal Investigators: Paul Mackenzie, lead, Fermilab; Carleton De Tar, University of Utah; Norman Christ, Columbia University; Richard Brower, Boston University; Robert Edwards, Jefferson Lab

Lattice quantum chromodynamics (QCD) calculations are the scientific instrument to connect observed properties of hadrons (particles containing quarks) to fundamental laws of quarks and gluons and critically important to decadal particle and nuclear physics experiments. To elucidate tiny effects of yet-to-be-discovered physics beyond the standard model, particle physics needs QCD simulations accurate to ~0.10% and nuclear physics needs QCD-computed properties and interactions of hadrons and light nuclei on much larger volumes than possible today.
