Abstract. High momentum transfer electrodisintegration of polarized and unpolarized deuterium targets, d(e, e'p)n is studied. We show that the importance of final state interactions FSI, occuring when a knocked out nucleon interacts with the other nucleon, depends strongly on the momentum ~, of the spectator nucleon. In particular, these FSI occur when the essential contributions to the scattering amplitude arise from internucleon distances 1.5 fm. But the absorption of the high momentum 7* may produce a point like configuration, which evolves with time. In this case, the final state interactions probe the point like configuration at the early stage of its evolution. If the point like configuration is still small after propagating about 1.5 fm, the FSI are suppressed. The result is that significant color transparency effects, which can either enhance or suppress computed cross sections, are predicted to occur for Q2>4GeV2. We suggest searching for color transparency phenomenon by examining ratios of experimentally measured quantities. Possible theoretical uncertainties of the calculations, including those due to the deuteron wave function and relativistic effects, are found to be small.

“…The nucleon swelling discussed in this work refers to the increase of the quark confinement size. Such quark confinement enlargement is present in the multiquark cluster models [41][42][43][44][45], while a smaller quark deconfinement is predicted in the Quark-Meson Coupling (QMC) model [46][47][48], and the nuclear potential model [54][55][56]. In the multiquark cluster model, the heavy nuclei favor the formations of large multi-nucleon clusters containing 3N (N = 1, 2, 3...) valence quarks.…”

“…The size of the estimated nucleon swelling from experiments and from various models are listed in Table I. We see that several models predict such effects of a few percent, such as the QMC model [48], the binding potential model [54], the Skyrmion model [55], the quark-nucleon interaction model [56], the chiral quark-soliton model [57], the chiral symmetry restoration model [58], the weak stretching model [59], the PLC-suppression model [60], and the statistical model [61].…”

Flavor-dependent EMC effect from a nucleon swelling model

et al. 2019

We present our results for a flavor-dependent EMC effect based on the nIMParton nuclear PDFs, in which the x-dependence is described with a nucleon swelling model. The nuclear correction from nucleon swelling is considered through a modification of the initial valence quark distributions instead of a dynamical rescaling. To probe the flavor-dependence of the model, the experimental observables are calculated applying nIMParton nuclear modifications for various experiments: parity-violating deep inelastic scattering on nuclear target, pion-induced Drell-Yan, and W-boson production in proton-nucleus collisions. In addition, we present the expected effect for the spectator-tagged deep inelastic scattering process, which will be performed by the CLAS12 collaboration with the ALERT detector.I.

The deformation of the interacting nucleon in the Skyrme model

Changes in the nucleon shape are investigated by letting the nucleon deform under the strong interactions with another nucleon. The parameters of the axial deformations are obtained by minimizing the static energy of the two nucleon system at each internucleon distance $ R $. It is shown that the intrinsic quadrupole moment of the interacting proton, $Q_{p}$, is about $0.02 fm^2$ at distances near $R \sim 1.25 $ fm.Comment: 11 pages, uudecode, gzip, tar, latex, 3 eps figures, accepted for the publication by Phys.Lett.
