Event details

Identifying mathematical functions which may appear in the evaluation of a Feynman integral is an important step for the algorithmic computation of these integrals. In the past this approach has been very successful for amplitudes, which can be expressed in terms of multiple polylogarithms. However, in theories with massive particles the class of functions of multiple polylogarithms is no longer sufficient. In this talk I will give an introduction of what lies beyond the class of multiple polylogarithms and discuss the generalisation of (multiple) polylogarithms to the elliptic case.

About Particle Physics Theory seminars

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..
