A preliminary final state analysis of a sample of in-flight annihilations into three and five charged pions is presented. The partial-wave analysis of three-prong data confirms previous interpretations of the resonance, from annihilations at rest. Concerning five-prong events our analysis favours spin 0 for the already reported ζ(1480) state, but more refined calculations are underway. At high momenta, the five-prong data show some evidence for a possible spin 2 state at 1640 MeV/c2 decaying in ρ°ρ°.

Abstract
A preliminary final state analysis of a sample of in-flight annihilations into three and five charged pions is presented. The partial-wave analysis of three-prong data confirms previous interpretations of the resonance, from annihilations at rest. Concerning five-prong events our analysis favours spin 0 for the already reported ζ(1480) state, but more refined calculations are underway. At high momenta, the five-prong data show some evidence for a possible spin 2 state at 1640 MeV/c2 decaying in ρ°ρ°.File in questo prodotto:
