Abstract
Production in hadronic collisions of ordinary and possible new heavy charged or neutral vector bosons decaying to final states containing an ${e}^{+}$ or ${e}^{\mathrm{\ensuremath{-}}}$ is studied in supersymmetric QCD. Parton distributions are computed for a number of assumptions about scalar-quark and gluino masses. For foreseeable energies, the scalar-quark--anti-scalar-quark annihilation contribution is at most a few percent of the quark-antiquark annihilation contribution. However, increased vector-boson decay widths and faster evolution of quark distributions in the supersymmetric case decrease cross sections by a factor of as much as 2--3 relative to the ordinary case. Other, more detailed observables are only marginally affected.
