Feynman integrals associated to elliptic curves

S. Weinzierl (THEP, Mainz)

Feynman integrals are indispensable for precision calculations in quantum field theory. But they are notoriously difficult to calculate. While we do have methods to compute any one-loop Feynman integral analytically, already at two-loops there are Feynman integrals for which the known methods fail. The first obstruction one encounters is related to elliptic curves, and for this reason the Feynman integrals not tractable by standard methods are known as ``elliptic’’ Feynman integrals. In this talk I will review our current knowledge about Feynman integrals associated to elliptic curves.
