Abstract

The helicity density matrix elements ρ₀₀ of ρ(770)^± and w(782) mesons produced in Z⁰ decays have been measured using the OPAL detector at LEP. Over the measured meson energy range, the values are compatible with 1/3, corresponding to a statistical mix of helicity -1, 0 and +1 states. For the highest accessible scaled energy range 0.3 < x_E < 0.6, the measured ρ₀₀ values of the ρ^± and the w are 0.373 ± 0.052 and 0.142 ± 0.114, respectively. These results are compared to measurements of other vector mesons.

N2 - The helicity density matrix elements ρ00 of ρ(770)± and w(782) mesons produced in Z0 decays have been measured using the OPAL detector at LEP. Over the measured meson energy range, the values are compatible with 1/3, corresponding to a statistical mix of helicity -1, 0 and +1 states. For the highest accessible scaled energy range 0.3 < xE < 0.6, the measured ρ00 values of the ρ± and the w are 0.373 ± 0.052 and 0.142 ± 0.114, respectively. These results are compared to measurements of other vector mesons.
