Double-Copy Structure of One-Loop Open-String Amplitudes
Carlos R. Mafra, Oliver Schlotterer
In this Letter, we provide evidence for a new double-copy structure in one-loop amplitudes of the open superstring. Their integrands with respect to the moduli space of genus-one s…
Fermionic one-loop amplitudes of the RNS superstring
Seungjin Lee, Oliver Schlotterer
We investigate massless n-point one-loop amplitudes of the open RNS superstring with two external fermions and determine their worldsheet integrands. The contributing correlation f…
New BCJ representations for one-loop amplitudes in gauge theories and gravity
Song He, Oliver Schlotterer, Yong Zhang
We explain a procedure to manifest the Bern-Carrasco-Johansson duality between color and kinematics in -point one-loop amplitudes of a variety of supersymmetric gauge theories.…
Twisted elliptic multiple zeta values and non-planar one-loop open-string amplitudes
Johannes Broedel, Nils Matthes, Gregor Richter +1
We consider a generalization of elliptic multiple zeta values, which we call twisted elliptic multiple zeta values. These arise as iterated integrals on an elliptic curve from whic…
