Description
Top quark production at hadron colliders is a treasure for a) experimentalists, b) phenomenologists and c) formal field theorists. In this talk you can expect to learn how these three sides of particle physics are connected to a calculation with two "firsts": the first ever hadron collider calculation at NNLO with 1) massive fermions and 2) more than two coloured partons at Born level. After I describe the formal developments that led to this result (including, for example, developments in IR singularities of gauge amplitudes and connection to soft gluon (Sudakov) resummation) I will demonstrate its phenomenological power in both SM and BSM applications. I'll conclude with a brief discussion about the future of precision hadron collider physics.
