Abstract
We present cross-section formulas for the production of scalar fermions, photinos, and W and Z gauginos (including heavy W and Z gauginos) by electron-positron collisions. We have considered general mixings, so that most of our results are general and not dependent on any particular model (except that we assume a relatively light photino). The mass eigenstates in the chargino sector have been studied in particular detail. Numerical results for beam energies varying from present-day DESY PETRA energies to beyond CERN LEP II energies are presented.
