Abstract

In the context of the little Higgs models, we discuss single production of the new charged gauge bosons in association with top quark at the CERN Large Hadron Collider (LHC). We find that the new charged gauge bosons $W_{H}^{-}$ and X^-, which are predicted by the littlest Higgs model and the $SU(3)$ simple model, respectively, can be abundantly produced at the LHC. However, since the main backgrounds coming from the processes $pp\rightarrow t\bar{t}+X$ and $pp\rightarrow tW^{-}+X$ are very large, the values of the ratios N_W and N_X are very small in most of the parameter space. It is only possible to detect the signal of the gauge boson $W_{H}^{-}$ via the process $pp\rightarrow gb+X\rightarrow tW_{H}^{-}+X$ at the LHC in a small region of the parameter space.
