JaxoDraw: A graphical user interface for drawing Feynman diagrams. Version 2.0 release notes

A new version of the Feynman graph plotting tool JaxoDraw is presented. Version 2.0 is a fundamental rewrite of most of the JaxoDraw core and some functionalities, in particular importing graphs, are not backward-compatible with the 1.x branch. The most prominent new features include: drawing of Bézier curves for all particle modes, on-the-fly update of edited objects, multiple undo/redo functionality, the addition of a plugin infrastructure, and a general improved memory performance. A new LaTeX style file is presented that has been written specifically on top of the original axodraw.sty to meet the needs of this this new version. PROGRAM SUMMARY Title of program: JaxoDraw Distribution format: gzipped tar archive Does the new version supersede the previous version?: Yes Nature of problem: Existing methods for drawing Feynman diagrams usually require some 'hard-coding' in one or the other programming-or scripting language. It is not very convenient and often time consuming, to generate relatively simple diagrams. Method of solution: A program is provided that allows for the interactive drawing of Feynman diagrams with a graphical user interface. The program is easy to learn and use, produces high quality output in several formats and runs on any operating system where a Java Runtime Environment is available. Reasons for the new version: A variety of new features and bug fixes. Summary of revisions: Major revisions since the last published user guide were versions 1.1, 1.2 and 1.3 with several minor bug-fix releases in between. Restrictions: To make use of the latex export/preview functionality, a latex style file has to be installed separately. Certain operations (like internal latex compilation, Postscript preview) require the execution of external commands that might not work on untested operating systems. Typical running time: As an interactive program, the running time depends on the complexity of the diagram to be drawn.
