Abstract | |||||||||
| ProminentK ¯ K resonances observed in the in-flight annihilation of ¯ pp intoK+K−π0 include f2(1270), f0(1500), f 2 (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 bymeans 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 f 2(1525), are found to be suppressed by an order of magnitude compared to f0(1500) and f2(1270), respectively. | |||||||||
