Theoretical Nuclear and Hadronic Physics — Perturbative and Non-perturbative QCD

Research Summary
The work of Professor Metz is mainly focused on the (multi-dimensional) quark and gluon structure of strongly interacting objects such as the proton. His interests and projects in this field include conceptual questions related to the parton structure of hadrons, QCD factorization for high-energy scattering processes, data analyses using modern Monte Carlo tools, theory support for lattice-QCD calculations, the properties of parton correlation functions, and studies of power corrections.
