Superstring Z' boson in the production of jets in e(-)e(+) annihilation

The production of jets in the annihilation of an arbitrarily polarized e(-)e(+) pair is studied in the superstring E(6) model. Expressions for helicity amplitudes, effective cross sections, and various polarization characteristics of the processes e(-)e(+) --> q (q) over bar g and e(-)e(+) --> (q) over tilde qg are obtained. A detailed analysis of polarization effects in the production of charmed and beautiful quarks (scalar quarks) is performed. It is found that the study of polarization characteristics in the processes e(-)e(+) --> q (q) over bar g and e(-)e(+) --> (q) over tilde qg is of paramount importance for extracting information about the properties of an additional superstring boson.
