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; .

The H1 and ZEUS Collaborations report new results on elastic VM cross-section and trajectory determination. Elastic VM production appears to be independent of the photon polarization. The presence of non-zero shrinkage in the photoproduction of J/psi indicates the presence of soft physics. Accumulated data do not accommodate a universal Pomeron trajectory. The steepness of the x dependence of elastic VM production with changing Q^2+M_V^2 is similar to that of F_2 with changing Q^2.

The steepness of the x dependence of elastic VM production with changing Q^2+M_V^2 is similar to that of F_2 with changing Q^2.
