Three-nucleon forces, which compose an up-to-date subject in few-nucleon systems, provide a good account of the triton binding energy and the cross section minimum in proton-deuteron elastic scattering. However, three-nucleon forces do not explain spin observables such as the nucleon and deuteron analyzing powers, suggesting serious defects in their spin dependence. We study the spin structure ...

We consider the Generalized Parton Distributions for spin-1 nuclei in general and on the deuteron in particular. We use the impulse approximation to obtain a convolution model for them. Sum rules are used to check the validity of the approach and to estimate the importance of higher Fock-space states in the deuteron. Numerical predictions for the Beam Spin Asymmetry in deeply virtual Compton sc...

For 52 target nuclei with deuteron as projectile, we calculate the reaction cross sections and elastic scattering angular distributions, as well as the χ values for 11 kinds of deuteron optical model potentials: our global deuteron optical potentials and 10 folding optical potentials calculated with 2 phenomenological global nucleon optical potentials given by Koning et al(KD) and by Varneret a...

Light nuclei have much smaller binding energy compared to the temperature of the system created in heavy-ion collisions. Consequently, the distributions of light nuclei can be used to probe the freeze-out properties, such as correlation volume and local baryon density of the medium created in high-energy nuclear collisions. In this paper, we report the results of deuteron and anti-deuteron prod...

The deuteron deep inelastic unpolarized structure function FD 2 is calculated using the Wilson operator product expansion method. The long distance behaviour, related to the deuteron bound state properties, is evaluated using the Bethe–Salpeter equation with one particle on–mass–shell. The calculation of the ratio F 2 D/2F 2 N is compared with other convolution models showing important deviatio...

This paper contains suggestions for experiments with usage of the Spin Physics Detector (SPD) at first stage SPD NICA Programme developing JINR. Double polarized pp-, dd- and pd- collisions c.m.s. NN energies 3.4-10 GeV, which will be accessible initial experiments, allow one to study spin dependence interaction, search multiquark states double strangeness, charm beauty thresholds, short-range ...

Background: An isoscalar $pn$ pair is expected to emerge in nuclei that have similar proton and neutron numbers it may be a candidate for deuteron ``cluster.'' There is, however, no experimental evidence it.Purpose: The purpose of this paper construct new reaction model the $(p,pd)$ including breakup elementary process reformation by final-state interactions. How these processes contribute obse...

New results for the T20-component of tensor-analyzing power incoherent negative pion photoproduction are presented. The experiment was performed electron beam energy 800 MeV at VEPP-3 storage ring in 2021. To extract T20-component, we used asymmetry with respect to change sign tensor polarization deuteron target. Identification reaction events carried out by detection two protons coincidence. E...
