Title: Evaluating Loop Integrals via Sector Decomposition and Expansion by Regions with pySecDec

Abstract: As a result of the experimental accuracy reached in modern particle physics, theoretical uncertainties have become the main limiting factor for an increasing number of experimental analyses. Therefore the precise evaluation of higher order corrections is needed. This talk will provide an overview of two widely used techniques to evaluate loop integrals, namely Sector Decomposition and Expansion by Regions, and will discuss their implementation in the program pySecDec. The new release of pySecDec will be presented along with its new features.
