Venue: Blokhintsev Hall (4th floor), Bogoliubov Laboratory of Theoretical Physics
Seminar topic: «Five-Particle Phase-Space Integrals in Massless QCD»
Speaker: Andrei Pikelner (BLTP)
Abstract:
We present results for the calculation of the fully- inclusive five-particle phase-space integrals in the massless QCD. The evaluation method is based on a numerical solution of the difference recurrence relations in space-time dimensionality variable with high precision and reconstruction of the analytical results using PSLQ algorithm. Discussed asymptotics of the phase-space integrals in the limit of infinite space-time dimension and various numerical cross-checks of obtained result.
