The left-right twin Higgs (LRTH) model predicts the existence of the neutral Higgs bosons (h, φ0), which can be produced in pairs (φ0φ0, hh, φ0h) via γγ collisions at the next generation e+eInternational Linear Collider (ILC). Our numerical results show that the production cross section of the neutral Higgs boson pair φ0φ0 can reach 8.8 fb. The subprocess γγ→φ0φ0 might be used to test the LRTH model in future ILC experiments.
