Single-valued Integration, Double Copy and Superstring Amplitudes (in genus zero and one)
Open and closed superstring amplitudes at tree-level and one-loop have striking mathematical relations leading to the concept of single-valued integration and double copy in genus zero and one. Likewise at the physical side these properties lead to relations between gauge and gravitational amplitudes.
