Differential Equations for Feynman Graph Amplitudes
It is by now well established that, by means of the integration by part identities [1], all the integrals occurring in the evaluation of a Feynman graph of given topology can be expressed in terms of a few independent master integrals. It is shown in this paper that the integration by part identities can be further used for obtaining a linear system of first order differential equations for the...
متن کاملWorld Graph Formalism for Feynman Amplitudes
A unified treatment of Schwinger parametrised Feynman amplitudes is suggested which addresses vertices of arbitrary order on the same footing as propagators. Contributions from distinct diagrams are organised collectively. The scheme is based on the continuous graph Laplacian. The analogy to a classical statistical diffusion system of vector charges on the graph is explored.
متن کاملFeynman Amplitudes in Mathematics and Physics
These are notes of lectures given at the CMI conference in August, 2014 at ICMAT in Madrid. The focus is on some mathematical questions associated to Feynman amplitudes, including Hodge structures, relations with string theory, and monodromy (Cutkosky rules).
متن کاملCalculating Transition Amplitudes from Feynman Diagrams
When one thinks of quantum field theory, one’s mind is undoubtedly drawn to Feynman diagrams. The näıve view these diagrams as merely a concise and standardized way of describing collisions and processes. Feynman diagrams, however, encode a great deal of information, for each one corresponds exactly to the probability amplitude of the transition it describes. In other words, it is easily possib...
متن کاملFeynman Amplitudes and Landau Singularities for 1-loop Graphs
The subject of Feynman amplitudes with variable momenta and non-zero masses has been studied by physicists since the 1950’s. In the interim, new mathematical methods involving Hodge structures and variations of Hodge structures have been developed. The purpose of this paper is to apply these techniques to the study of amplitudes and Landau singularities in momentum space. While the techniques w...
