Abstract

Fermilab experiment E-760 has confirmed the f₂(1520) state in the 3π^o final state in antiproton-proton annihilations in-flight (~3.0 to 3.6 GeV c.m. energy), seen previously by Crystal Barrel and other groups at CERN at rest. The f₂(1520) is also seen in its 2π^o decay mode in the 2π^oη channel and 2η decay mode in the π^o2η channel. There are indications of this state in the 3η decay channel. The invariant mass spectrum is rich in states near 2 GeV, and amplitude and spin/parity analysis of the Dalitz plot is in progress in this mass region.
