Event details
Precision calculations in quantum field theory rely very often on perturbation theory and thus on the computation of Feynman integrals. Two of the basic algorithms are integration-by-parts and the method of differential equations. In this talk I show how the efficiency of these algorithms can be improved by taking geometric information of the Feynman integrals into account. The method does not require any prior knowledge of the geometry and merely amounts to counting poles and residues.
About Particle Physics Theory seminars
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
