Event details

Polylogarithms appear abundantly in physics, and in particular they often arise as Feynman integrals. Given a suitable ("linearly reducible") integral representation, these can be computed algorithmically; for example with the program HyperInt. I will explain the concept of linear reducibility, summarize classes of Feynman integrals for which such a representation is known and also show applications to the calculation of gluon exchange webs.

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..
