Fermilab experiment E-760 has confirmed the f2(1520) state in the 3πo 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 2πo decay mode in the 2πoη channel and 2η decay mode in the πo2η 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. © 1993.

Abstract
Fermilab experiment E-760 has confirmed the f2(1520) state in the 3πo 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 2πo decay mode in the 2πoη channel and 2η decay mode in the πo2η 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. © 1993.File in questo prodotto:
