The reaction π−p → ωN∗o at 2.75 GeV/c

At 2.75 GeV/c, the reaction π-p → π-pπ-π+πo is dominated by the quasi-two-bosy final states ωN∗o33 (1236 MeV) and ωN∗o13 (1518 MeV). There is no production of the B- enhancement. The spin space density matrix elements for the ωN∗o33 final state are compared with those for other reactions.
