Simpler Superstring Scattering
Kiyoung Lee, Warren Siegel
We give a new, manifestly spacetime-supersymmetric method for calculating superstring scattering amplitudes, using the ghost pyramid, that is simpler than all other known methods.…

Conquest of the ghost pyramid of the superstring
Kiyoung Lee, Warren Siegel
We give a new Becchi-Rouet-Stora-Tyutin operator for the superstring. It implies a quadratic gauge-fixed action, and a new gauge-invariant action with first-class constraints. The…
