J. Layssac et al., STRONG RESONANCES EFFECTS AND FUTURE HIGH-PRECISION MEASUREMENTS, Physical review. D. Particles and fields, 48(9), 1993, pp. 4037-4044
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.
