Study of E/i decays into K(K)over-bar pi in the reaction (p)over-bar-p->E/i pi pi

The results of the preliminary analysis of 4840 (K (K) over bar pi)pi pi events, from a data sample of 24 million (p) over bar p annihilations at rest in a gaseous hydrogen target at NTP, collected with the OBELIX spectrometer at LEAR (CERN), are presented. The presence of two pseudoscalar states in the region around 140 MeV/c(2), already seen, for the first time, in (p) over bar p annihilations at rest from analysis of a data set taken with a liquid hydrogen target, is confirmed, The lighter mass resonance decays mainly into K (K) over bar pi, while the higher mass 0(-+) state decays only into K*(K) over bar. A sizable fraction of direct K*(K) over bar production, from the initial P-wave protonium state (about twice the value in liquid hydrogen), is observed, as expected. No significant evidence for an axial vector emerges from this preliminary analysis.
