摘要：

The Dashen-Weinstein sum rule for deviations from the Goldberger-Treiman relation allows a measurement of ms/ m ̂. The present data indicate ms/ m ̂ ≤10.6±4.2, implying a considerably lower value of the condensate 〈qq̄〉 than usually belived. A new precision KN scattering experiment designed in view of a better determination of the coupling constants gΛNK and gΣNK is urgently called for. © 1990.
