Top Quark Pair Production via (un)Polarized Photon Collisions in the Littlest Higgs Model with T-parity at the ILC

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-bar 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.
