0 A Feynman Diagram Analyser DIANA – Graphic Facilities
New developments concerning the extension of the recently introduced (1) Feynman diagram analyser DIANA are presented. Recent high precision experiments require, on the side of the theory, high-precision calculations resulting in the evaluation of higher loop diagrams in the Standard Model. For specific processes thousands of multiloop Feynman diagrams do contribute. Of course, the contribution...
متن کاملParallel computation of Feynman diagrams with DIANA
Co-operation of the Feynman DIagram ANAlyzer (DIANA) with the underlying operational system (UNIX) is presented. We discuss operators to run external commands and a recent development of parallel processing facilities and an extension in the spirit of a component model.
متن کاملPercolation on a Feynman Diagram
In a recent paper [1] we investigated Potts models on “thin” random graphs – generic Feynman diagrams, using the idea that such models may be expressed as the N → 1 limit of a matrix model. The models displayed first order transitions for all q > 2, giving identical behaviour to the corresponding Bethe lattice. We use here one of the results of [1] namely a general saddle point solution for a q...
متن کاملA UML Class Diagram Analyzer
Automatic analysis of UML models constrained by OCL invariants is still an open research topic. Especially for critical systems, such tool support is important for early identification of errors in modeling, before functional requirements are implemented. In this paper, we present ideas on an approach for automatic analysis of UML class diagrams, according to a precise semantics based on Alloy,...
متن کاملHopf algebra approach to Feynman diagram calculations
The Hopf algebra structure underlying Feynman diagrams which governs the process of renormalization in perturbative quantum field theory is reviewed. Recent progress is briefly summarized with an emphasis on further directions of research.
