The Number Theory of Superstring Amplitudes
  OKC/Nordita High-Energy Physics Theory seminar

Monday 31 August 2015
from 13:15 to 14:15
at 122:026
Speaker : Oliver Schlotterer (AEI Potsdam)
Abstract : This talk explores the cross fertilization between number theory and superstring perturbation theory. I will first discuss multiple zeta values and their relations from the viewpoint of iterated integrals on a genus zero surface. They enter the alpha' expansion of superstring tree amplitudes in a pattern that can be understood in terms of their generating series and Hopf algebra structures. We will conclude with a glimpse of iterated integrals on a torus which give rise to elliptic analogues of multiple zeta values and find a natural appearance in one-loop amplitudes of the open superstring.
