  • Location: Higgs Centre Seminar Room,

Event details

This talk is about the two-loop integral reduction and unitarity, in the framework of dimensional regularization. We present a new efficient method, based on computational algebraic geometry, to compute maximal cut, non-maximal cut and the complete reduction of two-loop diagrams. Possible future developments, like simplification at some specific dimension and differential algebra method, will also be discussed.

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..
