Action density of the QCD vacuum from a Lattice QCD simulation

Summary

Quarks are the fundamental particles that make up most of ordinary matter. They are bound together by the strong nuclear force, mediated by the exchange of gluons as described by Quantum Chromo Dynamics (QCD). By using simulations we are able to study QCD's properties. The calculation is performed by constructing a discrete four dimensional space-time grid (the lattice) and then solving the QCD equations of motion on state-of-the-art high performance computers. Yet unknown physics can be discovered as discrepancies between our predictions and experimental measurements freshly coming in from e.g. the large experimental facilities at CERN. This talk will give a short overview of our current understanding of particle physics and how we are using high performance computing to understand its mysteries.
