Electromagnetic Form Factors of the Deuteron in the Dibaryon Model of the \(\mathbf{NN}\) Interaction

Abstract

The electromagnetic form factors of the deuteron have been calculated within the dibaryon model for nuclear forces, which is based on the resonance mechanism of six-quark bag (dibaryon) formation in \(NN\) collisions. The calculations take into account both single-nucleon currents (impulse approximation) and additional contributions induced by the formation of an intermediate dibaryon. Two versions of the dibaryon model, from 2002 and 2022, have been used for the form factor calculations. It is shown that both versions of the model reproduce the experimental data well for all three deuteron form factors in the momentum transfer region \(Q<0.8\) GeV/\(c\). At higher \(Q\), the predictions of the different versions of the model diverge, with one version (2002) providing a better description of the magnetic form factor and the other (2022) better describing the charge form factor. Possible reasons for the observed discrepancy between theoretical calculations and experimental data for large momentum transfers are discussed.
