  In this paper we evaluate, in the context of the linear BESS model the
cross-section for the double Higgs-strahlung process. We find that, within the
bounds given by the actual experimental data, significant deviations with
respect to the SM may arise. In the linear BESS model not only the
self-couplings of the Higgs are modified, but also the Z-Higgs couplings. We
think that this is a generic feature of any extension of the SM and, in our
opinion, it should be kept in mind in analyzing the future data on the process
studied here.
