Computational Elementary Particle Physics

    The computational physics research group "Particle Physics" at the John von Neumann-Institute for Computing (NIC) at DESY is concerned with non-perturbative computations of quantum field theories. A particular emphasis is quantum chromodynamics (QCD) as our theory of the strong interactions between quarks and gluons.

    To study QCD non-perturbatively, the theory is constructed on a discrete Euclidean lattice leading to the so-called lattice QCD formulation of QCD.
    Besides being a theoretically sound definition of QCD, lattice QCD allows also a numerical evaluation of the path integral which is taken to quantize the system.
