IBP reduction via Gröbner bases in a rational double-shift algebra
Mohamed Barakat, Robin Brüser, Tobias Huber +1
We report on an approach to integration-by-parts reduction based on Gröbner bases. We establish the underlying noncommutative rational double-shift algebra wherein the integration-…

The full angle-dependence of the four-loop cusp anomalous dimension in QED
Robin Brüser, Christoph Dlapa, Johannes M. Henn +1
The angle-dependent cusp anomalous dimension governs divergences coming from soft gluon exchanges between heavy particles, such as top quarks. We focus on the matter-dependent cont…
