Polarization correlations in electron-positron reactions

Abstract

We study the angular dependence of one-particle inclusive reactions with polarized electron-positron beams. It is observed that spin-$\frac{1}{2}$ and spin-1 partons, with zero anomalous magnetic moments, give the same angular distribution. The production of ordinary vector mesons, with zero anomalous magnetic moments, has also the same angular dependence and provides a candidate for a new component to the annihilation cross section. Present observations do not exclude such a component. A separate section elaborates on general properties of the quasielastic reaction for beams with arbitrary polarizations.
