Description

We show how to construct the moduli-space integrands for one-loop superstring amplitudes from the knowledge of 10D field-theory loop integrands in the BCJ form. Our map provides an alternative to intricate computations involving worldsheet supersymmetry. This construction is a one-loop higher-point analogue of a recent conjecture for the three-loop four-point superstring amplitude.
