Analyzing Power in the Reactionsp+d→d+pandp+p→d+πat GeV Energies

Abstract

We have used a polarized proton beam to measure the analyzing power for $\mathrm{pd}$ backward elastic scattering at incident kinetic energies of 0.68, 1.03, and 1.53 GeV and for the reaction $p+p\to d+\pi$ at 1.03 GeV. The data indicate that several mechanisms dominate $\mathrm{pd}$ backward elastic scattering over this energy range.
