Abstract: I will present the first numerical computation of two-loop amplitudes based on the unitarity method. During this presentation, I will focus on the organisation of the calculation in a form that is suitable for the unitarity method, taking the four-gluon process as an example. This procedure applies more generally to two-loop computations of phenomenologically relevant signatures at hadron colliders.
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
