High Energy Quantumelectrodynamics II,r calculation based upon Feynman diagrams give one an unambiguous method to compare the theory with observation. The agreement so far has been without exception. One likes to believe that there is a basis for the calculational rules in quantum field theory. However, so far the attempt to produce suc

S-Matrix Theory of Electromagnetic Interactions,formulation of the laws of physics in terms of the .-number scattering matrix elements. The scattering matrix itself is defined in terms of the (free physical) particle properties such as momenta, spin, and other quantum numbers which are numbers labelling the representations and states of symmetry

Electromagnetic Properties of Hadrons in the Static ,, Model,ng partly a bare proton and partly a bare proton with a virtual . pion around it. This picture was never very successful in explaining the electromagnetic properties of the baryons. The reason is that the well-explored outer part of the pion cloud does not contain much charge and magnetic moment and

Theories with Gauge Groups, variable phase functions can be viewed as a generalization of the gauge invariance of first kind (with constant phase) which forces the introduction of the electromagnetic potential, so that the gauge transformation on the matter field can be cancelled by the gauge transformation of the potential.

An Introduction to Theories of Integration over Function Spaces,ite number of variables dates back to a paper written already in 1914 by . [. 1914], where he proposed to make use of a functional formulation for the dynamics of many particle systems and continuous media.

Theory of Laser Radiation,ace the atoms by two-level systems (spins) and ignore the other levels. Secondly we start with matter of . = -0 ∞ (all spins up, e.g. in the state of higher energy), which means we consider flashing ruby-lasers rather than continous Ne-He-lasers. Finally we shall ignore the atomistic structure of matter and treat it as a continuum.

The Zero Mass Limit of a Charged Particle in Quantum Electrodynamics,ome information on the high energy limit of the theory. We are also interested in the question whether the theory exists for zero mass charged particles. The work I will discuss has been done in collaboration with . [1]. A detailed analysis of the zero mass problem was first given by . [2].

Streitst die gesamte Palette des technisch und verlegerisch Möglichen erprobt, dabei manche Gebiete intensiv und nachhaltig gepflegt, andere — uns heute »interessanter« erscheinende — oft ungeschickt betreut und zu schnell aufgegeben.
