Multiparticle amplitudes at one-loop: an algebraic/numeric approach
arXiv:hep-ph/0407003 · doi:10.1016/j.nuclphysbps.2004.09.027
Abstract
We discuss algebraic/numeric methods to compute one-loop corrections for multiparticle/jet production cross sections. By using efficient reduction algorithms a compact expression for the gggγγ-> 0 amplitude is obtained. Further a numerical approach for 6-point 1-loop diagrams is presented.
