Vector-to-Pseudoscalar and Meson-to-Baryon Ratios in Hadronic Z Decays at LEP
Protvino, 2000.-p.7, figs.2, tables 1, refs.:41.


Mass dependences of the total production rates per hadronic Z decay of all light-flavour hadrons measured so far at LEP are extrapolated to the zero mass limit ($m$=0) using phenomenological laws of hadron production related to the spin, isospin, strangeness content and mass of the particles. The vector-to-pseudoscalar and meson-to-baryon ratios at $m$=0 are found to be: $\rho^+ /\,3\,\pi^+ = 1.2\,\pm\,0.3$ and $\pi^+ /\,p = 2.9\,\pm\,0.3$, in a good agreement with the predictions of quark combinatorics.
