Seminar of the department “Theory of Fundamental Interactions”

Date and Time: Wednesday, 1 December 2021, at 11:00 AM

Venue: online seminar on Zoom, Blokhintsev Conference Hall (4th floor), Bogoliubov Laboratory of Theoretical Physics

Seminar topic: “Sunrise integrals in terms of elliptic polylogarithms”

Speaker: A. V. Kotikov

Abstract:

A set of two-loop sunrise master integrals with two different internal masses is studied under pseudo-threshold kinematics (i.e. q²=m² in Euclidean space). Results in terms of elliptic polylogarithms are found in all orders of the dimensional regulator.
