Abstract

Vector mesons produced in the reaction e +e −→V+X at √ s=29 GeV were isolated by observing D ∗ mesons through the D ∗+→ D 0π + decay. The D 0 decay modes used are D 0→K3 π, K π, K π, and K π( π 0). 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.
