# The Equal-Mass Banana Integral and Integrals of Modular Forms

#### The Equal-Mass Banana Integral and Integrals of Modular Forms

- Event time: 2:00pm
- Event date: 12th February 2020
- Speaker: Dr Robin Marzucca (IPPP Durham)
- Location: Higgs Centre Seminar Room, Room 4305, James Clerk Maxwell Building (JCMB) James Clerk Maxwell Building Peter Guthrie Tait Road Edinburgh EH9 3FD GB

### Event details

Great progress in the analytic computation of scattering amplitudes was made in recent years utilising our good understanding of polylogarithms. With demands for higher precision calculations including massive states, we are now often confronted with functional dependences that lie beyond the realm of polylogarithms. We investigate the relation between different Riemann surfaces and the connected function spaces, define a useful basis of functions for the computation of scattering amplitudes and will show how to compute the equal-mass banana integral in terms of these functions.

### 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..
