The authors' main claim The potential has a minimum of $V = -{1\over{32 g^2}}$ which is 60% of the predicted exact minimum of $V=-{1\over{2\pi^2 g^2}}$ from D-brane arguments.
The compiled record
The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The abstract, sentence by sentence
A classical action for open superstring field theory has been proposed which does not suffer from contact term problems. After generalizing this action to include the non-GSO projected states of the Neveu-Schwarz string, the pure tachyon contribution to the tachyon potential is explicitly computed. The potential has a minimum of $V = -{1\over{32 g^2}}$ which is 60% of the predicted exact minimum of $V=-{1\over{2\pi^2 g^2}}$ from D-brane arguments.
