The research activity of the Institute of Theoretical Physics II concentrates on central topics in hadron physics namely understanding the structure, properties and dynamics of strongly interacting hadronic matter. For this we employ a broad spectrum of analytical methods of modern theoretical physics including but not limited to effective field theories, expansion in the number of colors, perturbative QCD, resummation of leading logarithms etc., which, in certain cases, are complemented by numerical simulations.
Currently, the main research directions of the institute members include spontaneously broken approximate chiral symmetry of QCD and its manifestations in low-energy properties and dynamics of hadrons, theory of nuclear forces and applications to few- and many-body systems, lattice simulations of nuclear dynamics based on chiral effective field theory, low-energy electroweak few-nucleon reactions, pion-nucleon dynamics, quark mass dependence of hadronic observables (especially in connection with lattice-QCD calculations and the theory of Big Bang nucleosynthesis), effective field theories for spin-3/2 fields, hadron spectroscopy (especially in connection with exotic baryons), topological configurations (instantons, solitons, dyons, etc.) in non-abelian quantum field theories and gravity, hard QCD processes (extraction, theoretical analysis, modeling and applications of parton distributions and their generalization, multi-parton dynamics). These investigations are related to experiments running or being planned at BaBar (SLAC, Stanford, USA), BES (Beijing, China), COMPASS (CERN, Genf, Switzerland), ELSA (Bonn, Germany), HIGS (Durham, USA), JLab (Newport News, USA), LHC (CERN, Genf, Switzerland), MAMI (Mainz, Germany), MAX-lab (Lund, Sweden), PANDA (FAIR, Darmstadt, Germany) and Spring-8 (Japan).

Our institute is a member of the Sino-German CRC 110 "Symmetries and the Emergence of Structure in QCD" and is involved into the collaborative project NuSTAR R&D supported by BMBF.
Further, there are several bilateral research projects with scientists in Dubna, Irkutsk and St. Petersburg in Russia and Cracow in Polen.
