Abstract In the littlest Higgs model with T-parity (LHT), some new particles, such as the T-odd mirror quarks and goldstone bosons, can contribute to various observables. We calculate their contribution to Zcc coupling. Some observables are related to Zcc coupling, for example, the effective vector and axial−vector Zcc coupling constants (gVc,gAc) and c−quark forward-backward asymmetry (AcFB). We give our predictions about gVc,gAc in the LHT model and show the allowed regions of the mirror quark masses based on the experimental data of gVc−gAc. Then, we present an explanation of AcFB.
