Single production of vector-like top partner in the Wb channel at eγ collision in the LHT model

In the framework of the littlest Higgs Model with T-parity (LHT), we investigate the single production of vector-like top partner T+ decaying to Wb in the leptonic channel at the high energy e gamma collision. We utilize the polarized electron beam and photon beam to enhance the signal and propose a search strategy by performing a detector simulation. On the basis of the current limits from the precision electroweak data and Higgs data, we find that the top partner mass can be excluded up to 1350 (1380) GeV with integrated luminosity of 1000 fb(-1) and 1400 (1470) GeV with integrated luminosity of 3000 fb(-1) for the root s = 2.0 TeV (2.4 TeV) at the 2 sigma level. If the center-of-mass energy can be improved to 3.0 TeV, the limits on the top partner mass will reach 1450 (1550) GeV with integrated luminosities of 1000 (3000) fb(-1).
