All-order differential equations for one-loop closed-string integrals and modular graph forms
Jan E. Gerken, Axel Kleinschmidt, Oliver Schlotterer
We investigate generating functions for the integrals over world-sheet tori appearing in closed-string one-loop amplitudes of bosonic, heterotic and type-II theories. These closed-…

One-loop open-string integrals from differential equations: all-order alpha'-expansions at n points
Carlos R. Mafra, Oliver Schlotterer
We study generating functions of moduli-space integrals at genus one that are expected to form a basis for massless -point one-loop amplitudes of open superstrings and open boso…

All-order alpha'-expansion of one-loop open-string integrals
Carlos R. Mafra, Oliver Schlotterer
We present a new method to evaluate the -expansion of genus-one integrals over open-string punctures and unravel the structure of the elliptic multiple zeta values in its coeff…
