Electromagnetic Productions of the Hyperon and the Hypertriton Using Real and Virtual Photons
Open accessAbstract
The electromagnetic production of kaon-hyperon on the nucleon has been studied by means of a diagrammatic technique. All important resonances listed by the Particle Data Group up to spin 5/2 are included in this analysis. To extract the unknown coupling constants the new data from CLAS, SAPHIR, LEPS, and GRAAL collaborations have been used. In this paper we report on the preliminary results of this analysis. The available elementary model along with the modern nuclear wave functions have been used to analyze the process of photoas well as electroproduction of the hypertriton off the 3He. In this analysis we found that a proper treatment of Fermi motion is essential for describing the process, whereas the few available experimental data favor the assumption that the initial nucleon is off-shell and the final hyperon is on-shell. The influence of the higher partial waves in this process is also investigated. We also discuss the prospect of investigating kaon production off 4He.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
A spinning particle is not perfectly pointlike; in particular, its center of charge and center of mass do not coincide.
“We can add that a spinning particle is not perfectly pointlike. In particular, its center of charge and center of mass do not coincide [91-96].”
From <i>Zitterbewegung</i> of massless particles (2022) · cites this paper as [92]
The Introduction discusses kaon production and quark models, while §3 (Nuclear Operator) discusses spin-averaged nuclear quantities. Neither addresses whether a spinning particle is pointlike or whether its centers of charge and mass coincide. Searches for those centers and for a displacement between them found no relevant passage in our copy. (LLM, conf=0.76)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
