The One-loop Open Superstring Massless Five-point Amplitude with the Non-Minimal Pure Spinor Formalism
Carlos R. Mafra, Christian Stahn
We compute the massless five-point amplitude of open superstrings using the non-minimal pure spinor formalism and obtain a simple kinematic factor in pure spinor superspace, which…
Fermionic superstring loop amplitudes in the pure spinor formalism
Christian Stahn
The pure spinor formulation of the ten-dimensional superstring leads to manifestly supersymmetric loop amplitudes, expressed as integrals in pure spinor superspace. This paper expl…
Superfield integrals in high dimensions
Michael B. Green, Kasper Peeters, Christian Stahn
We present an efficient, covariant, graph-based method to integrate superfields over fermionic spaces of high dimensionality. We illustrate this method with the computation of the…
D3-branes on the Coulomb branch and instantons
Michael B. Green, Christian Stahn
The relative coefficients of higher derivative interactions of the IIB effective action of the form C^4, (D F_5)^4, F_5^8, ... (where C is the Weyl tensor and F_5 is the five-form…
