Abstract：
In the littlest Higgs model with T-parity, we discuss the pair production of the T-odd top partner (T_) that decays almost 100% into the top quark and the lightest T-odd particle (A_H). Considering the current constraints, we investigate the observability of the T-odd top partner pair production through the process pp→T_T_→ttA_HA_H in the final states with two leptons at 14 TeV LHC. We analyze the signal significance and found that the lower limits on the T-odd top partner mass are approximately 1.2 TeV, 1.3 TeV, and 1.4 TeV at the 2σ confidence level at 14 TeV LHC with an integrated luminosities of 30 fb^-1, 100 fb^-1, and 300 fb^-1, respectively. This lower limit can be increased to approximately 1.5(1.6) TeV if we used 1000(3000) fb^-1 of the integrated luminosity.
