Algebraic Approach to Bare Nucleon Matrix Elements
Sven Zschocke, Burkhard Kampfer, Guenter Plunien
An algebraic method for evaluating bare nucleon matrix elements of quark operators is proposed. Thereby, bare nucleon matrix elements are traced back to vacuum matrix elements. The…
Renormalization of the two-photon vacuum polarization and the self energy vacuum polarization for a tightly bound electron
Sven Zschocke, Guenter Plunien, Gerhard Soff
The renormalization method of Bogoljubov-Parasiuk-Hepp-Zimmermann (BPHZ) is used in order to derive the renormalized energy shift due to the gauge invariant Källén-Sabry diagram of…
Quantum radiation in external background fields
Ralf Schützhold, Guenter Plunien, Gerhard Soff
A canonical formalism is presented which allows for investigations of quantum radiation induced by localized, smooth disturbances of classical background fields by means of a pertu…
