Abstract

Possible oblique effects from vector particles that are strongly coupled to the known gauge bosons are calculated for the case of final hadronic states produced at future $e^{+} e^{-}$ colliders, using a formalism that was recently proposed and that exploits the information and the constraints provided by CERN LEP 1 results. Combining the hadronic channels with the previously analyzed leptonic ones we derive improved limits for the masses of the resonances that, in technicolorlike cases, would range from one to two TeV for a 500 GeV linear collider, depending on the assumed theoretical constraints.
