Title: Applications of Elliptic Calculus

Abstract: Recently there has been a surge in the study of Feynman integrals which evaluate to functions beyond polylogarithms. In this talk, I will present a tour of the elliptic toolkit for Feynman integrals, starting from a Feynman parametrisation and ending on a neat representation in terms of "pure functions" defined on the elliptic curve. To this end, I will present in detail a non-planar two-loop triangle with a massive loop relevant to the production of a top pair. The tools I will present are useful in general for Feynman integrals of the elliptic kind.
