Fermion Pair Production in e⁺e⁻ Collisions from 192 to 208 GeV and Limits on Physics beyond the Standard Model — •Richard Cavanaugh and Guillaume Leibenguth — Kirchhoff Institut für Physik, Schröderstraße 90, 69120 Heidelberg

Preliminary results on cross sections and forward-backward asymmetries for hadronic and leptonic events produced in e⁺e⁻ collisions at centre-of-mass energies from 192 to 208 GeV are given. These results combined with previous results obtained at lower energies lead to constraints upon physics beyond the Standard Model such as four-fermion contact interactions, leptoquarks, Z′ bosons, R-parity violating squarks and sneutrinos, and TeV scale quantum gravity.
