Abstract

The study of the K^±K⁰ _missπ^±π ⁺π^- channel (7016 events), from p̄p 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 KK̄π mass region, the well established f₁(1285), decaying to a₀(980) π, the second, the 1⁺⁺ component of the old puzzling E/i, the f_i(1420), decaying mainly to K*K̄, seen for the first time in pp annihilation at rest. The analysis confirms the dominant production of the pseudoscalar η(1405), decaying mainly to (Kπ)sK̄, and the existence of a second pseudoscalar in the same mass region, the η(1460), decaying mainly to K*K̄.
