Notes on the Wess-Zumino-Witten-like structure: L ∞ triplet and NS-NS superstring field theory [PDF]
In the NS-NS sector of superstring field theory, there potentially exist three nilpotent generators of gauge transformations and two constraint equations: it makes the gauge algebra of type II theory somewhat complicated.

Cutkosky rules for superstring field theory [PDF]
A bstractSuperstring field theory expresses the perturbative S-matrix of superstring theory as a sum of Feynman diagrams each of which is manifestly free from ultraviolet divergences.

The S-matrix of superstring field theory [PDF]
A bstractWe show that the classical S-matrix calculated from the recently proposed superstring field theories give the correct perturbative S-matrix. In the proof we exploit the fact that the vertices are obtained by a field redefinition in the large ...

Superstring field theory with open and closed strings [PDF]
We construct Lorentz invariant and gauge invariant 1PI effective action for closed and open superstrings and demonstrate that it satisfies the classical BV master equation.

Superstring field theory and the Wess-Zumino-Witten action [PDF]
We describe a notion of “higher” Wess-Zumino-Witten-like action which is natural in the context of superstring field theories formulated in the large Hilbert space.

Equivalence of two contour prescriptions in superstring perturbation theory [PDF]
Conventional superstring perturbation theory based on the world-sheet approach gives divergent results for the S-matrix whenever the total center of mass energy of the incoming particles exceeds the threshold of production of any final state consistent ...

Superstring Loop Amplitudes from the Field Theory Limit. [PDF]
We propose a procedure to determine the moduli-space integrands of loop-level superstring amplitudes for massless external states in terms of the field theory limit. We focus on the type II superstring.
