Abstract

Results are presented of an analysis of the reactions pp → p_f(K⁰_SK ^± π ∓ )p_s and pp → p_f(K⁰_SK⁰_Sπ ⁰)p_s at 450 GeV/c. Clear f₁(1285) and f₁(1420) signals are seen and a spin parity analysis shows that both have I^GJ^PC = 0⁺ 1 ⁺⁺. The f₁(1285) decays to a₀(980)π and the f₁(1420) decays to K * K̄. Both states have a similar dependence as a function of dPT consistent with what has been observed for other qq states. Evidence is also presented for a K *K̄ decay mode of the η₂(1620).
