Possible measurements of the spin one observables in elastic dN, dd collisions at the NICA deuteron beams

摘要

The report shows the possibilities of studying the spin one observables in the elastic dN and dd interactions at the NICA collider of the VBLHEP JINR. The use of the colliding deuteron beams would allow us to carry out the measurements of the differential cross sections I~0 (dN, dd) of the elastic scattering of unpolarized deuterons and the differential cross sections I~(pol) (dN, dd) and the vector A_y(E_d,θ) and tensor A_(yy)(E_d, θ) and A_(xx)(Ed.θ) analyzing powers in elastic collisions of the vector and tensor polarized deuterons. The planned luminosity of the colliding polarized deuteron beams will provide sufficiently high elastic events counting rate. The use of the colliding beams of the polarized deuterons for the spin one dN and dd observables research has a number of significant advantages in comparison with the experiments with the "fixed" target. The angular acceptance of the collider detector covers the full solid angle 4π radians while the wide ranges of the energies of the dN, dd interactions and the 4-momentum transfer squared are available.
