Karl Jansen - The Quest for Solving QCD: Simulating quark and gluon interactions on supercomputers

RTG Seminar on May 25th, 2016

The strong interaction of quarks and gluons is described theoretically within the framework of Quantum Chromodynamics (QCD). The most promising way to evaluate QCD for all energy ranges is to formulate the theory on a 4-dimensional Euclidean space-time grid, which allows for numerical simulations.

We shall demonstrate that since the invention of this approach of lattice-QCD by K. Wilson the conceptual, algorithmic and supercomputer developments have progressed so much that today realistic simulations of lattice-QCD become possible, bringing us close to a, at least, numerical solution of QCD. As one example, we will show results for the hadron spectrum.

We will also discuss the status of lattice QCD calculations for the internal structure of hadrons and describe the very new aproach of directly computing parton distribution functions on the lattice.
