A Search for Axial Vector in pbar pK+- K0{miss} pi+- pi+ pi- Annihilations at Rest in Gaseous Hydrogenat NTP

The study of the (K+/-Kmiss0) pi(-/+)pi(+)pi(-) channel (7016 events), from <(p)over bar p> annihilations in a gaseous hydrogen target at NTP, with the OBELIX spectrometer at LEAR (CERN), is presented. A spin-parity analysis provides evidence for two axial vectors, one in the low <K(K)over bar pi> mass region, the well established f(1)(1285), decaying to alpha(u)(980) pi, the second, the 1(++) component of the old puzzling E/t, the f(1)(1420), decaying mainly to K*(K) over bar, seen for the first time in <(p)over bar p> annihilation at rest. The analysis confirms the dominant production of the pseudoscalar eta(1405), decaying mainly to (K pi)(s) (K) over bar, and the existence of a second pseudoscalar in the same mass region, the eta(1460), decaying mainly to K*(K) over bar.
