Abstract

Vector mesons produced in the reaction e⁺e^-→V+X at √s=29 GeV were isolated by observing D^* mesons through the D^*+→D⁰π⁺ decay. The D⁰ decay modes used are D⁰→K3π, Kπ, Kπ, and Kπ(π⁰). The data, which correspond to an integrated luminosity of 300 pb^-1, were collected by the High Resolution Spectrometer at PEP. Spin density matrix elements for the D^* meson are measured as a function of the energy sharing variable Z_D^*. There is no evidence for alignment of D^* mesons produced in e⁺e^- annihilation at our energy.
