From elliptic multiple zeta values to modular graph functions: open and closed strings at one loop

Abstract We relate one-loop scattering amplitudes of massless open- and closed-string states at the level of their low-energy expansion. The modular graph functions resulting from integration over closed-string punctures are observed to follow from symmetrized open-string integrals through a tentati...
