Title: Series expansion methods for Feynman integrals, and their application to Higgs plus jet integrals

Abstract: I will discuss the computation of the non-planar master integrals for Higgs + jet production with full heavy quark mass dependence, which was carried out in arXiv:1907.13156 and arXiv:1911.06308. These integrals depend on multiple scales, and include elliptic sectors, which makes them challenging to compute either analytically or numerically. I will discuss how they may be computed efficiently from their differential equations in terms of iterated truncated one-dimensional series expansions, which may be used to obtain high precision results (tens of digits). I will also review the series expansion methods in more generality, and discuss additional examples of their application.
