The Origins of Matter on Near-Exascale Supercomputing

Pavlos Vranas | 17-ERD-002

Executive Summary

Our goal is to perform supercomputer simulations of large-scale lattice quantum chromodynamics in order to illuminate a great scientific mystery: the lack of antimatter relative to matter in the universe. Filling this gap in the Standard Model of particle physics will inform research in all missions related to nuclear science.
