摘要
We study the top-quark pair production via polarized and unpolarized photon collisions at the International Linear Collider in the context of the littlest Higgs model with T-parity.We calculate the production cross section of the process γγ→ tt and find the effects can be more significant in the (——) polarized photon collision mode than in other collision modes,and the relative correction can be expected to reach about 1% in the favorable parameter space.
