A preliminary final state analysis of a sample of np in-flight annihilations into three and five charged pions is presented. The partial-wave analysis of three-prong data confirms previous interpretations of the Ax/f2(1520) resonance, from ppBAR annihilations at rest. Concerning five-prong events our analysis favours spin 0 for the already reported zeta(1480) state, but more refined calculations are underway. At high nBAR momenta, the five-prong data show some evidence for a possible spin 2 state at 1640 MeV/c2 decaying in rho(o)rho(o).

Abstract

A preliminary final state analysis of a sample of np in-flight annihilations into three and five charged pions is presented. The partial-wave analysis of three-prong data confirms previous interpretations of the Ax/f2(1520) resonance, from ppBAR annihilations at rest. Concerning five-prong events our analysis favours spin 0 for the already reported zeta(1480) state, but more refined calculations are underway. At high nBAR momenta, the five-prong data show some evidence for a possible spin 2 state at 1640 MeV/c2 decaying in rho(o)rho(o).
