A Mathematica Interface for FormCalc-generated Code

This note describes a Mathematica interface for Fortran code generated by FormCalc. The interfacing code is set up automatically so that only minuscule changes in the driver files are required. The interface makes a function to compute the cross-section or decay rate available in Mathematica. This function depends on the model parameters chosen for interfacing in the Fortran code.Comment: 6 page

New Features in FormCalc 4

FormCalc is a Mathematica package for the automatic computation of tree-level and one-loop Feynman amplitudes. It accepts diagrams generated by FeynArts, simplifies them, and generates a complete Fortran code for their numerical evaluation. Version 4 includes new features which enhance performance, convenience of use, and modularity/code reusability.Comment: 5 pages, Talk given at the 7th DESY Workshop On Elementary Particle Theory: Loops And Legs In Quantum Field Theory, Zinnowitz, Germany, 25-30 Apr 200

Excursions into FeynArts and FormCalc

Programming techniques which extend the capabilities of FeynArts and FormCalc are introduced and explained using examples from real applications.Comment: 5 pages, proceedings contribution to Loops and Legs 2006, Eisenach, German

News from FormCalc and LoopTools

The FormCalc package automates the computation of FeynArts amplitudes up to one loop including the generation of a Fortran code for the numerical evaluation of the squared matrix element. Major new or enhanced features in Version 5 are: iterative build-up of essentially arbitrary phase-spaces including cuts, convolution with density functions, and uniform treatment of kinematical variables. The LoopTools library supplies the one-loop integrals necessary for evaluating the squared matrix element. Its most significant extensions in Version 2.2 are the five-point family of integrals, and complex and alternate versions.Comment: 5 pages, to appear in the proceedings of the 7th International Symposium on Radiative Corrections (RADCOR05), Shonan Village, Japan, 200

Genetic diversity and pathogenicity of the grey mould fungus Botrytis

Genetic diversity and pathogenicity of the grey mould fungus Botrytis Botrytis spp., causes pre- and postharvest decay on strawberry crops. Botrytis spp. isolates from several German strawberry-growing fields, which received several fungicide treatments against Botrytis per season, were analyzed to determine their sensitivity against botryticides.Universidad de Malaga.

Geometric continuous patch complexes

A theory of geometric continuity of arbitrary order is presented. Conditions of geometric continuity at a vertex where a number of patches meet are investigated. Geometric continuous patch complexes are introduced as the appropriate setting for the representation of surfaces in CAGD. The theory is applied to the modelling of closed surfaces and the fitting of triangular patches into a geometric continuous patch complex
