Vertical Integration from the Large Hilbert Space
Theodore Erler, Sebastian Konopka
We develop an alternative description of the procedure of vertical integration based on the observation that amplitudes can be written in BRST exact form in the large Hilbert space…
One Loop Tadpole in Heterotic String Field Theory
Theodore Erler, Sebastian Konopka, Ivo Sachs
We compute the off-shell 1-loop tadpole amplitude in heterotic string field theory. With a special choice of cubic vertex, we show that this amplitude can be computed exactly. We o…
Open Superstring Field Theory on the Restricted Hilbert Space
Sebastian Konopka, Ivo Sachs
Recently an action for open superstring field theory was proposed where the Neveu-Schwarz sector is formulated in the large Hilbert space while the Ramond sector lives in a restric…
The S-Matrix of superstring field theory
Sebastian Konopka
We 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 t…
