Two point amplitude for closed superstrings
Sitender Pratap Kashyap
We present a prescription for computing the tree-level two-point amplitude of closed strings in the pure spinor superstring formalism, thereby completing the analysis of such super…

Tension between string amplitude prescriptions with presumed spacetime supersymmetry
Thales Azevedo, Alessandro Georgoudis, Renann Lipinski Jusinskas +1
We analyze an alternative prescription for computing tree level scattering amplitudes in the pure spinor superstring. Proposed by Berkovits, and inspired by an earlier work by Lee…
