摘要：After a brief review of the various approaches available for the automated computation of multiparticle scattering amplitudes at the one-loop level, in this presentation we describe the main features of the GOSAM (Golem/Samurai) framework. The GOSAM approach combines a ddimensional extension of the integrand-level reduction method and improved tensorial techniques, with an automated generation of amplitudes via Feynman diagrams. GOSAM can be used to generate and evaluate one-loop corrections in both QCD and electro-weak theory, and offers the flexibility to link general model files for theories Beyond the Standard Model. The discussion will be accompanied with examples of applications.
