Top quark pair production via $e^{+}{e}^{-}$ collision in the littlest Higgs model with T-parity at the ILC

Abstract

In the littlest Higgs model with T-parity, we studied the contributions of the new particles to the top-quark pair production via $e^{+}{e}^{-}$ collision at the International Linear Collider. We calculated the top-quark pair production cross section and found this process can generate significantly relative correction. The result may be a sensitive probe of the littlest Higgs model with T-parity.
