In the framework of the unified compositeness of leptons, quarks and Higgs bosons, supplemented with the hypothesis of the vector boson dominance of the SM gauge interactions, restrictions on the universal residual fermion–boson and boson–boson interactionsare investigated. Manifestations of the universal interactions in the W+W− and ZH boson pair production at the 2 TeV e+e− linear collider are studied. Definite signaturesof these interactions are exposed, and their relations to the nonstandard triple gaugeinteractions are considered. It is shown that the unified substructure could be tested atthe collider in these processes up to the compositeness scale [Formula: see text], which liesin the naturally preferred deca-TeV region. Importance of the optimal angular cutoffsand the polarized beams is found.

We study pair-production as well as the triple self-couplings of the neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM) at the future International Linear e+e-Collider (ILC) and Compact Linear Collider (CLIC). The analysis is based on the reactions [Formula: see text] with hi= h, H, A. We evaluate the total cross-section for both [Formula: see text] and calculate the total number of events considering the complete set of Feynman diagrams at tree-level. We vary the triple couplings κλhhh, κλHhh, κλhAA, κλHAA, κλhHHand κλHHHwithin the range κ = -1 and +2. The numerical computation is done for the energies expected at the ILC with a center-of-mass energy 500, 1000, 1600 GeV and a luminosity 1000 fb-1. The channels [Formula: see text] and [Formula: see text] are also discussed to a center-of-mass energy of 3 TeV and luminosities of 1000 fb-1and 5000 fb-1.
