摘要
Motivated by the search for flavor-changing neutral current（FCNC） top quark decays at the LHC,we calculate the rare Higgs three body decay H→Wbc induced by top-Higgs FCNC coupling in the littlest Higgs model with T-parity（LHT）.We find that the branching ratio of H→Wbc in the LHT model can reach O（10^-7） in the allowed parameter space.
