Prominent KK¯ resonances observed in the in-flight annihilation of p¯p into K+K−π0 include f2(1270), f0(1500), f2′(1525), ϕ(1680)/ρ(1700) and a state at 1750 MeV/c2 consistent with f0(1710). The reaction cross sections σ(p¯p→X(K+K−)π0) are obtained by means of a partial wave analysis. When these are combined with known KK¯ partial widths, the resulting production rates of presumably non-nn¯ 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. |
