摘要：

We perform an update of the bounds on the parameters of the BESS model, which describes a possible strong electroweak breaking, by including latest experimental informations. The obtained bounds can be compared with predictions from special cases, corresponding to technicolor and extended technicolor. In spite of some ambiguities, it appears that conventional QCD-scaled technicolor with N(TC) technicolors and N(d) technidoublets is excluded at 90% CL for N(TC)N(d) larger than approximately 12.
