Progress in FDC Project

TL;DR
This paper presents FDC, an integrated framework that automates tree-level perturbative calculations from model specification to numerical results. It details a modular pipeline (gmodel, diag, amp, kine, gmprocess) that derives Feynman rules for SM and SUSY, generates amplitudes and phase-space integrals, and produces event generators compatible with Les Houches interfaces. It also highlights specialized sub-projects (FDC-PWA, FDC-EMT, FDC-NRQCD) expanding FDC to partial-wave analyses, effective meson models, and NRQCD for heavy quarkonia. The work enables streamlined, cross-checked theory-to-simulation workflows for current and future colliders, with results accessible via an HTTP-enabled homepage.
Abstract
The FDC is a general-purpose program package for Feynman Diagram Calculation. We outline previous successes in calculations and focus on its recent progress about automatic deduction the Feynman rules for first principle model, especially for the supersymmetric model, proper evaluation of the rates of multi-final-particle processes and the event generators in the SM and MSSM. A few special applications are presented. The FDC-homepage shows an automatic translation of the FDC results into the HTTP version.
