Abstract
The tensor polarisation of Ï mesons produced in the pdâHe3Ï reaction has been studied at two energies near threshold. The He3 nuclei were detected in coincidence with the Ï0Ï+Ïâ or Ï0γ decay products of the Ï. In contrast to the case of Ï-meson production, the Ï 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.
