Multi-gluon one-loop amplitudes using tensor integrals
arXiv:0905.1005 · doi:10.1088/1126-6708/2009/07/088
Abstract
An efficient numerical algorithm to evaluate one-loop amplitudes using tensor integrals is presented. In particular, it is shown by explicit calculations that for ordered QCD amplitudes with a number of external legs up to 10, its performance is competitive with other methods.
