Formcalc 6
The new features and improvements in FormCalc Version 6 as well as some recent additions in FeynArts for easier diagram selection are reported.
متن کاملNew Features in Formcalc 4
FormCalc [ 1] is a Mathematica package for the calculation of Feynman amplitudes. It prepares the amplitudes generated by FeynArts [ 2] for numerical evaluation. This consists of an algebraic simplification step, including e.g. the tensor reduction and the calculation of fermionic traces, and a code generation step, where the complete Fortran code for the evaluation of the squared matrix elemen...
متن کاملExcursions into FeynArts and FormCalc
FeynArts [1] and FormCalc [2] are programs for the generation and calculation of Feynman diagrams. The main problem they solve is the computation of the cross-section for a given process, and indeed this is meanwhile a heavily automated procedure that requires little user input. Feynman diagrams have a lot of other uses, however, and this note shows some examples of how to extend the capabiliti...
متن کاملNews 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...
متن کاملA Mathematica interface for FormCalc-generated code
This note describes a Mathematica interface for Fortran code generated by Form-Calc. 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.
