The linear BESS model and the double Higgs-strahlung production

Abstract

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.
