This quantity comprises the contributions to the foreign summer season INSTITUTE ON THEORETICAL PHYSICS 1980 held from September 1st to September twelfth in undesirable Honnef, Germany. This Institute was once equipped via Wuppertal college. It was once the 11th in a sequence of summer time colleges on particle physics performed through German Universities. The Institute was once aimed to check the current prestige of gauge theories in easy particle physics, with emphasis either at the phenomenological and formal elements. the 1st a part of the amount covers the hot development within the improvement of perturbative tools either in quantum chromodynamics (QCD) and style dynamics (QFD). purposes to on hand info from electron positron garage earrings and deep inelastic scattering are mentioned. the second one half provides new effects on classical suggestions and non-perturbative equipment in gauge theories and comparable box theories like non linear a-models. a truly topical account is given at the program of Monte Carlo tools inside of lattice gauge theories. at this time those tools seem to be the main promising strategy to determine the quark confinement speculation in the framework of non-Abelian gauge theories. the quantity is closed with a growth record at the current realizing of sup~rgravity and its relation to grand unification schemes. The lectures on Grand Unified Theories given via Dr. D. V. Nanopoulos on the undesirable Honnef assembly are available within the court cases of the 1980 Rencontre de Moriond (Ed. J. Tran Thanh Van).
