Depolarization Due to Target Motion
Abstract
The projection upon both of the lab scattering planes of a spin component along the center-of-mass angular momentum direction is computed for arbitrary target motion. The resulting depolarization of Λ hyperons produced by 1080-Mev/c pions on nuclear matter and on deuterons is presented as a function of production angle. At this energy, the polarization, if constant for all production angles, would be reduced to 85% and 95% of the original value in heavy nuclei with respect to the π×Λ and K×Λ planes, respectively. In deuterium, the reductions would be to 98.4% and 99.5% of the initial polarization.
