Modular Graph Forms and Scattering Amplitudes in String Theory
Jan E. Gerken
In this thesis, we investigate the low-energy expansion of scattering amplitudes of closed strings at one-loop level (i.e. at genus one) in a ten-dimensional Minkowski background u…

Generating series of all modular graph forms from iterated Eisenstein integrals
Jan E. Gerken, Axel Kleinschmidt, Oliver Schlotterer
We study generating series of torus integrals that contain all so-called modular graph forms relevant for massless one-loop closed-string amplitudes. By analysing the differential…
