### 摘要

In this work we calculate the leading electroweak (EW) corrections to the anomalous gtt̄ coupling in the littlest Higgs model with T-parity, by applying the Goldstone boson equivalence theorem. In the littlest Higgs model with T-parity model, such electroweak corrections arise from the loop diagrams of heavy fermions and the "would-be" Goldstone bosons. We further examine the EW corrections in the top quark pair production via the quark annihilation process at the LHC. The negative EW corrections in the standard model are partially canceled by the positive EW corrections from the loops of the new heavy particles, and the latter dominates in the large invariant mass of the top quark pair.
