CPT Student Seminar: An on-shell approach to one-loop amplitudes with massive fermions using unitarity cuts
30 January 2017 17:00 in OC218
We show how one-loop amplitudes with massive fermions can be computed using generalised unitarity. With this approach, the divergent on-shell cuts can be avoided and the additional information is extracted from the universal IR poles in 4-2ε dimensions and UV poles in 6-2ε dimensions. The aim is to address the formal problem of whether a purely on-shell formulation of amplitudes with masses is possible or not.

A gathering of mathematicians from the CPT group with physicists from IPPP, we meet to discuss our work in a relaxed and friendly environment.
