Abstract
In the littlest Higgs model with T-parity (LHT), we study the t-channel single top production in association with a Higgs boson at 8 and 14 TeV LHC. We find that the cross section can be enhanced obviously in this model compared to the Standard Model. By performing a simple parton-level simulation through \( pp\to t\left(\to {\ell}^{+}\nu b\right)h\left(\to b\overline{b}\right)j \) at 14 TeV LHC, we find that the observability of the signal is promising in the favorable parameter space.
