Description
In the framework of the minimal extended electroweak models inspired by superstrings, we evaluate the Zj boson hadronic and total decay widths, the values R ≡ σ(e+e- → hadrons)/σpt and R' ≡ σ(e+e- → hadrons)/σ(e+e- → l+l-) dependences on Z - Z' mixing parameter and on renormalization scheme parameters. All these values are measured now at LEP. Popular models are discussed for comparison. (author). 23 refs, 6 figs
