Towards the n-point one-loop superstring amplitude III: One-loop correlators and their double-copy structure
Carlos R. Mafra, Oliver Schlotterer
In this final part of a series of three papers, we will assemble supersymmetric expressions for one-loop correlators in pure-spinor superspace that are BRST invariant, local, and s…
Towards the n-point one-loop superstring amplitude II: Worldsheet functions and their duality to kinematics
Carlos R. Mafra, Oliver Schlotterer
This is the second installment of a series of three papers in which we describe a method to determine higher-point correlation functions in one-loop open-superstring amplitudes fro…
Towards the n-point one-loop superstring amplitude I: Pure spinors and superfield kinematics
Carlos R. Mafra, Oliver Schlotterer
This is the first installment of a series of three papers in which we describe a method to determine higher-point correlation functions in one-loop open-superstring amplitudes from…
Heterotic-string amplitudes at one loop: modular graph forms and relations to open strings
Jan E. Gerken, Axel Kleinschmidt, Oliver Schlotterer
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 t…
Berends-Giele currents in Bern-Carrasco-Johansson gauge for - and -deformed Yang-Mills amplitudes
Lucia M. Garozzo, Leonel Queimada, Oliver Schlotterer
We construct new representations of tree-level amplitudes in D-dimensional gauge theories with deformations via higher-mass-dimension operators and . Based on…
Closed strings as single-valued open strings: A genus-zero derivation
Oliver Schlotterer, Oliver Schnetz
Based on general mathematical assumptions we give an independent, elementary derivation of a theorem by Francis Brown and Clément Dupont which states that tree-level amplitudes of…
