As well known, if the Higgs boson were not observed at LHC, the technicolor model would be the most favorable candidate responsible for the symmetry breaking. To overcome some defects in the previous model, some extended versions have been proposed. In the TC2 model typical signature is existence of heavy H TC and technipion Π. A direct proof of validity of the model is to produce them at accelerator. Thus we study the production rates of e + e − → H TC Π 0 and e + e − → Π + Π − at ILC in the topcolor-assisted technicolor (TC2) model. In fact, there is a flood of models belonging to new physics, which can result in products with characteristics similar to H TC + Π of the TC2 model. Therefore to distinguish this model from others one may need to investigate some details by calculating the cross section to NLO. We indeed find that the NLO corrections are significant, namely the ratio δ = (σ NLO – σ LO )/σ LO in e + e − → H TC Π 0 exceeds 100% within a plausible parameter space.
