Measurements of Single and Double Spin Asymmetry in pp Elastic Scattering in the Coulomb Nuclear Interference Region at RHIC

ORAL

Abstract

We report a precise measurement of the single spin A$_{N}$ and double spin A$_{NN}$ asymmetries in pp elastic scattering in the Coulomb Nuclear Interaction region at several energies utilizing a polarized hydrogen jet target and the polarized proton beam at the Relativistic Heavy Ion Collider. We determine the energy dependence of the hadronic single spin flip and double spin flip amplitudes and the implication for Pomeron and Oderon exchanges.
