Abstract

The results of the preliminary analysis of 4840 (KK̄ π)ππ events, from a data sample of 24 million p̄p 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/c², already seen, for the first time, in p̄p annihilations at rest from analysis of a data set taken with a liquid hydrogen target, is confirmed, The lighter mass resonance decays mainly into KK̄ π, while the higher mass 0^-+ state decays only into K*K̄. A sizable fraction of direct K*K̄ 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.
