Determination of strange quark suppression in hadronic vacuum

  • Published:
Zeitschrift für Physik C Particles and Fields

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 <λ>=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.

  17. Consider the cross sectiondσ/dx for a resonanceR. A usual parameterization fordσ/dx isdσ/dx∼(1−x)ρ. Thex-spectrum of the daughter (D) is then obtained by convolutingσ R /dx overx, i.e.σ D /dx∼(1-x)p+1 and thus the spectrum will be softer for the daughter. Note that by helicity arguments a further softening of the daughter spectrum often results
