Abstract: Abstract: The tensor polarisation of ω mesons produced in the reaction has been studied at two energies near threshold. The nuclei were detected in coincidence with the or decay products of the ω. In contrast to the case of ϕ-meson production, the ω mesons are found to be unpolarised. This brings into question the applicability of the Okubo–Zweig–Iizuka rule when comparing the production of vector mesons in low energy hadronic reactions. [Copyright &y& Elsevier]
