Abstract
We develop a general formalism where the relevant oblique contribution s to a number of observables in future higher energies e+e- experiment s are expressed in the form of a once-subtracted dispersion integral. The necessary subtraction constants are always provided by model-indep endent CERN LEP 1 results. This procedure is particularly suitable for calculating possible effects from vector particles that are strongly coupled to the known gauge bosons. As a specific illustration, in the case of technicolorlike resonances we derive limits for their masses t hat are in the TeV range for a 500 GeV linear collider.
