“…Experiments at high energy accelerators (NICA (Nuclotron M), COSY, or GSI) with internal targets or thick targets and an ejected beam appear to be the most promising in this context. For example, spin dichroism magnitudes of approximately 0.15 were obtained in experiments [6,7] at Nuclotron M with an ejected deuteron beam with a momentum of 5 GeV/c.…”

“…One may neglect the deuteron binding energy (i.e., term in Hamiltonian (6)) in this approximation. As a result, Hamiltonian (6) is transformed into the follow ing form [5]: (7) where is the potential energy of interaction of a deuteron with a nucleus, and are the potential energies of nuclear interaction of a proton and a neutron with a nucleus, and is the potential energy of Coulomb interaction of a deuteron with a nucleus.…”

“…The effect of spin dichroism of deuterons was first observed for a beam with an energy of 5-20 MeV that passed through car bon targets [5]. The effect was later observed at Nuclo tron M (Joint Institute for Nuclear Research) for deu terons with a momentum of 5 GeV/c [6,7]. The observation of spin dichroism is attributed to the fact that the coefficient of absorption of deuterons in the spin state characterized by magnetic quantum number M = ±1 (the quantization axis is directed along the deuteron momentum) differs from that for deuterons with M = 0.…”

The phenomenon of birefringence (spin rotation and spin dichroism) of high energy deuterons is a macroscopic quantum effect similar to optical birefringence. Spin dichroism has already been observed experimentally. The contribution to spin dichroism produced by the interaction of the deuteron electric qua drupole moment with the electric field of a nucleus is considered. It is found that the effect is sensitive to the behavior of wave functions of the deuteron ground state at short distances.

“…In such experiments, the deuteron spin PoS(STORI11)028 "Optical" spin rotation phenomenon in a nuclear pseudomagnetic field V.Baryshevsky, A. Rouba dichroism brings about tensor polarization of the transmitted deuteron beam [2]. The experiments [8,9] were carried out this way. The main advantage of this method is its technical simplicity, because only an unpolarized deuteron beam, an unpolarized solid target, and a polarimeter are required.…”

Despite long-lasting study and seeming simplicity, the investigation of two-and three-particle interactions is still a topical problem. Because these investigations are very important, the experiments with antiproton, proton and deuteron interactions are included in scientific programs of modern accelerators COSY, GSI and LHC. In studding of these interactions, polarization observables sensible to different mechanisms of interaction are of particular interest as well as the differential reaction cross-section. Modern storage rings with a long lifetime of a beam permit one to carry out qualitatively new experiments with polarized beams and targets. Particularly, in the spin-filtering experiments [1] of antiprotons (protons, deuterons), it is possible to measure a spin-dependent part of a forward scattering amplitude [1]-[3]. Moreover, it is possible to measure the real part of a coherent elastic amplitude of proton (antiproton, deuteron) scattering at zero angle when the plane formed by the target polarization vector and the beam momentum direction lies in the orbit pane of the beam and the angle between these two vectors differs from 0, π or π/2 [2]. Measurement of the spin-dependent part of a forward scattering amplitude is possible

We propose to perform measurements of asymmetries of the DY pair"s production in collisions of non-polarized, longitudinally and transversally polarized protons and deuterons which provide an access to all leading twist collinear and TMD PDFs of quarks and anti-quarks in nucleons. The measurements of asymmetries in production of J/Ψ and direct photons will be performed as well simultaneously with DY using dedicated triggers. The set of these measurements will supply complete information for tests of the quark-parton model of nucleons at the QCD twisttwo level with minimal systematic errors. PAC Recommendations:….The PAC heard with interest a report on the preparation of the Letter of Intent "Spin physics experiments at NICA-SPD with polarized proton and deuteron beams" presented by I. Savin. The PAC is pleased to see the first steps toward formation of an international collaboration around the SPD experiment. The PAC regards the SPD experiment as an essential part of the NICA research program and encourages the authors of the Letter of Intent to prepare a full proposal and present it at one of the forthcoming meetings of the PAC. … --
