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

arXiv listing abstract v2. Results and the main claim are underlined; .

We study field theories in the limit that a compactified dimension becomes lightlike. In almost all cases the amplitudes at each order of perturbation theory diverge in the limit, due to strong interactions among the longitudinal zero modes. The lightlike limit generally exists nonperturbatively, but is more complicated than might have been assumed. Some implications for the matrix theory conjecture are discussed.

The paper
Original abstract

We study field theories in the limit that a compactified dimension becomes lightlike. In almost all cases the amplitudes at each order of perturbation theory diverge in the limit, due to strong interactions among the longitudinal zero modes. The lightlike limit generally exists nonperturbatively, but is more complicated than might have been assumed. Some implications for the matrix theory conjecture are discussed.

  • (The problems in compactifying any field theory along a null direction are discussed in, for example, [ref] and would in particular apply to the field theories considered here.) Recent work aiming at obtaining Schrödinger solutions without such a compact direction can be found in [ref] .

  • However, such a procedure is in general ill-defined, due to the coupling of the theory to zero modes on the circle which become infinitely strongly-coupled in the null limit [ref] [It may however be possible to avoid such pathologies for generic CFTs [ref] , although we will not need these results here. ].
