Abstract
We have analysed experimental data on (i)e+e− annihilation to hadrons, (ii) leptoproduction, (iii) hadron-hadron interactions, and (iv) heavy particle decays to determineSU(3) symmetry violation, i.e. the suppression factor (λ) for strange quark-antiquark pairs relative to\(u\bar u\) and\(d\bar d\) pairs in the hadronic vacuum. Inclusive particle ratios, i.e.K/π ratios at largex and ratios between the inclusive production rates of relevant resonances, yield similar values for λ, the weighted mean being =0.29±0.02. No significant energy dependence of λ is observed. We also find that the average net electric charge measurements for lepton produced quark jets are consistent with the above value of λ.
