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 √s_pp= 3 ÷5.5 GeV, may be associated with the formation of exotic eight-quark 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 correlation in elastic pn scattering in the same kinematics. The possibility of obtaining this data from the reaction d d→ pnp with two polarized deuterons on NICA SPD is considered in this paper.
