Diagrammatica: the Path to Feynman Diagrams
An easily accessible introduction to quantum field theory via Feynman rules in particle physics.
This author provides an easily accessible introduction to quantum field theory via Feynman rules and calculations in particle physics. His aim is to make clear what the physical foundations of present-day field theory are, to clarify the physical content of Feynman rules. The bo…
"A concise introduction to Feynman diagram techniques, this book shows how they can be applied to the analysis of complex many-particle systems, and offers a review of the essential elements of quantum mechanics, solid state physics and statistical mechanics. Alongside a detaile…

The basic purpose of the paper is to construct, for the indicated integrals, series expansions in terms of finite multiple integrals of increasing multiplicity ("generalized Dyson series''). The authors study in detail the character of these expansions in the case when the measu…
Die Dirac-Gleichung und Feynman-Graphen werden in Anlehnung an die Feynmanschen Originalarbeiten eingeführt. Viele Reaktionen der elektromagnetischen und schwachen Wechselwirkung werden vom Matrixelement bis zum Wirkungsquerschnitt explizit berechnet. Die Eichinvarianz in der El…
