One-loop open-string integrals from differential equations: all-order α′-expansions at n points
Abstract We study generating functions of moduli-space integrals at genus one that are expected to form a basis for massless n-point one-loop amplitudes of open superstrings and open bosonic strings. These integrals are shown to satisfy the same type of linear and homogeneous first-order differentia...
