NLO Cross Sections for the LHC using GOLEM: Status and Prospects

High Energy Physics - Phenomenology 2010-02-01 v2

Abstract

In this talk we review the GOLEM approach to one-loop calculations and present an automated implementation of this technique. This method is based on Feynman diagrams and an advanced reduction of one-loop tensor integrals which avoids numerical instabilities. We have extended our one-loop integral library golem95 with an automated one-loop matrix element generator to compute the virtual corrections of the process qqˉbbˉbbˉq\bar{q}\to b\bar{b}b\bar{b}. The implementation of the virtual matrix element has been interfaced with tree-level Monte Carlo programs to provide the full result for the above process.
