“…It would be interesting to extend the range of the measurements to larger p T , where the manifestation of non-nucleonic degrees of freedom is expected. Figure 4 presents the analyzing powers results in the d(d, 3 H)p and d(d, 3 He)n reactions obtained at RARF(RIKEN, Japan) at 200 and 270 MeV. The details of the experiment can be found in [3].…”

The investigation of the d, 3 H and 3 He spin structure has been performed at the RIKEN(Japan) accelerator research facility and VBLHEP(JINR) using both polarized and unpolarized deuteron beams. The experimental results on the analyzing powers studies in dp− elastic scattering, d(d, 3 H)p and d(d, 3 He)n reactions are presented. The vector and tensor analyzing powers for dp− elastic scattering at 880 and 2000 MeV are obtained at the Nuclotron(VBLHEP). The result on the analyzing powers A y , A yy of the deuteron at 2000 MeV are compared with relativistic multiple scattering model calculations. The data on the tensor analyzing powers for the d(d, 3 H)p and d(d, 3 He)n reactions obtained at E d = 200 and 270 MeV demonstrate the sensitivity to the 3 H, 3 He and deuteron spin structure. The essential disagreements between the experimental results and the theoretical calculations within the one-nucleon exchange model framework are observed. The wide experimental program on the study of the polar-ization effects in dp− elastic scattering, dp−nonmesonic breakup, d(d, 3 He)n, d(d, 3 H)p and d( 3 He, 4 He)p reactions using internal and extracted beam at Nuclotron is discussed.

The data on the vector Ay and tensor Ayy, Axx, and Axz analyzing powers of the dd → 3 Hen and dd → 3 Hp reactions obtained at intermediate energies at RARF (RIKEN, Japan) are presented. The high-precision experimental data are compared with the theoretical calculation within the one-nucleon exchange model by using the standard 3 He, 3 H, and deuteron wave functions. The data demonstrate the sensitivity to the short-range 3 He, 3 H, and deuteron spin structure. •¥¤¸É ¢²¥´Ò ¤ ´´Ò¥ ¶μ ¢¥±Éμ•´μ°Ay¨É¥´ §μ•´Ò³ Ayy, Axx, Axz ´ ²¨ §¨•ÊÕÐ¨³¸ ¶μ¸μ¡-μ¸ÉÖ³ •¥ ±Í¨° dd → 3 Hen¨ dd → 3 Hp, ¶μ²ÊÎ¥´´Ò¥ ¶•¨ ¶•μ³¥¦ÊÉμÎ´ÒÌ Ô´¥•£¨ÖÌ ¢ RARF (RIKEN, Ÿ ¶μ´¨Ö). ‚Ò¸μ±μÉμÎ´Ò¥ Ô±¸ ¶¥•¨³¥´É ²Ó´Ò¥ •¥ §Ê²ÓÉ ÉÒ¸• ¢´¨¢ ÕÉ¸Ö¸É¥μ•¥É¨Î¥¸±¨³• ¸Î¥É ³¨, μ¸´μ¢ ´´Ò³¨´ ³μ¤¥²¨μ¤´μ´Ê±²μ´´μ£μ μ¡³¥´ ¶•¨¨¸ ¶μ²Ó §μ¢ ´¨¨¸É ´¤ •É´ÒÌ ¢μ²-μ¢ÒÌ ËÊ´±Í¨°3He (3 H)¨¤¥°É•μ´. ±¸ ¶¥•¨³¥´É ²Ó´Ò¥ ¤ ´´Ò¥ ¤¥³μ´¸É•¨•ÊÕÉ ÎÊ¢¸É¢¨É¥²Ó´μ¸ÉÓ ±¸ ¶¨´μ¢μ°¸É•Ê±ÉÊ•¥ 3 He, 3 H¨¤¥°É•μ´ ´ ³ ²ÒÌ ³¥¦´Ê±²μ´´ÒÌ • ¸¸ÉμÖ´¨ÖÌ.

The major goal of the upgraded Nuclotron facility is to obtain the information on the equation-ofstate for dense nuclear matter playing a key role in the understanding of the collapse supernovae and neutron stars stability. These studies can be performed either in heavy ion collisions or via the short-range few nucleon correlations in deuteron induced reactions. The obtained experimental results and future program with the use of polarized deuteron beam and the internal target station are discussed. The polarization studies for the NN, NA and dA reactions with the extracted deuteron beam at the BM@N setup are proposed. The further extension of the polarization program at BM@N is related with the study of the in-medium modification of the polarization for the strange and multi-strange baryons and the spin alignment for vector mesons decaying in hadronic modes.
