文摘The littlest Higgs model with T-parity,which is called LHT model,predicts the existence of the new particles,such as heavy top quarks,heavy gauge bosons,and mirror fermions.We calculate the one-loop contributions of these new particles to the top quark chromomagnetic dipole moment (CMDM)ΔK.We find that the contribution of the LHT model is one order of magnitude smaller than the standard model prediction value.
