We present a description of the low energy &pgr;&pgr; scattering data using the Linear Sigma Model with K‐matrix unitarization. Then we carry out an analogous study of the strongly‐coupled minimal Higgs sector of the electroweak theory. We discuss the effect of the unitarization prescription on the WW or ZZ fusion processes and also suggest a related treatment for other Higgs production processes such as gluon fusion. © 2003 American Institute of Physics
