Abstract: An unexpectedly large double spin correlation with a sharp dependence on energy, found in elastic proton-proton scattering at large angles in the c.m.s. energy range GeV, may be associated with the formation of exotic octoquark resonances at the thresholds of the strangeness and charm production. For a deeper understanding of the dynamics of this process it is important to measure double spin asymmetry in elastic scattering in the same kinematics. A possibility of obtaining such data from the reaction with two polarized deuteron beams on NICA SPD is considered in this paper.
