The authors' main claim It is proven that up to possible surface terms, the only non-vanishing momentum-dependent amplitudes for the self-dual N=2 string in $R^{2,2}$ are the tree-level two and three-point functions, and the only non-vanishing momentum-independent amplitudes are the one-loop partition function and the tree-level two and four-point functions.

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.

  • Although the self-dual structure in four dimensions excludes real solutions in Lorentzian signature, it provides a good toy model to demonstrate some quantum aspects of gravity from different perspectives such as integrablility, string theories and scattering amplitudes (see, e.g., [ref] and references therein).
