DIANA and selected applications
New developments concerning the extension of the Feynman diagram analyzer
DIANA are presented. We discuss new graphics facilities, different approaches
to automation of momenta distribution and parallel processing facilities.
Furthermore applications to production and Bhabha scattering are
shortly discussed.Comment: Latex, 5 pages, 4 eps figures, uses included npb.sty, presented by at

FORM version 4.0
We present version 4.0 of the symbolic manipulation system FORM. The most
important new features are manipulation of rational polynomials and the
factorization of expressions. Many other new functions and commands are also
added; some of them are very general, while others are designed for building
specific high level packages, such as one for Groebner bases. New is also the
checkpoint facility, that allows for periodic backups during long calculations.
Lastly, FORM 4.0 has become available as open source under the GNU General
Public License version 3.Comment: 26 pages. Uses axodra

Sophisticated momenta mapping with DIANA
Details of recent developments of the Feynman diagram analyzer DIANA (DIagram
ANAlyser) are presented. Apart from some discussion about QGRAF and new
plotting features, we concentrate on a new sophisticated mechanism of momenta
mapping.Comment: 4 pages, 4 Encapsulated postscript figures, LaTeX2e, uses espcrc2.sty
(included). Talk given at ACAT0
A Feynman diagram analyzer DIANA: recent development
New developments concerning the extension of the Feynman diagram analyzer
DIANA are presented. We discuss new graphic facilities, application of DIANA to
processes with Majorana fermions and different approaches to automation of
momenta distribution.Comment: 2 pages, Latex using espcrc2.sty, 3 figures using 3 eps files.

A Feynman Diagram Analyser DIANA
A C-program DIANA (DIagram ANAlyser) for the automatic Feynman diagram
evaluation is presented. It consists of two parts: the analyzer of diagrams and
the interpreter of a special text manipulating language. This language is used
to create a source code for analytical or numerical evaluations and to keep the
control of the process in general.Comment: 20 pages, latex, 3 eps figure
