Heterotic-string amplitudes at one loop: modular graph forms and relations to open strings
Abstract We investigate one-loop four-point scattering of non-abelian gauge bosons in heterotic string theory and identify new connections with the corresponding open-string amplitude. In the low-energy expansion of the heterotic-string amplitude, the integrals over torus punctures are systematicall...
