Title: Feynman diagrams, beyond polylogarithms

Abstract: 

Much current work in particle physics involves Feynman diagrams whose integrals evaluate to polylogarithms, for which we have a good mathematical understanding. This talk is concerned with Feynman integrals that are not polylogarithms. In such cases, elliptic integrals, modular forms and Dirichlet L-series appear. I shall sketch some features of this new structure, in a way that presumes no prior mathematical knowledge.
