Abstract
Prominent K over(K, ̄) resonances observed in the in-flight annihilation of over(p, ̄) p into K+ K- π0 include f2 (1270), f0 (1500), f2′ (1525), φ{symbol} (1680) / ρ (1700) and a state at 1750 MeV/ c2 consistent with f0 (1710). The reaction cross sections σ (over(p, ̄) p → X (K+ K-) π0) are obtained by means of a partial wave analysis. When these are combined with known K over(K, ̄) partial widths, the resulting production rates of presumably non-n over(n, ̄) states, X = f0 (1710) and f2′ (1525), are found to be suppressed by an order of magnitude compared to f0 (1500) and f2 (1270), respectively.
