  We investigate the corrections of the littlest Higgs(LH) model and the SU(3)
simple group model to single top production at the CERN Large Hardon
Collider(LHC). We find that the new gauge bosons $W_{H}^{\pm}$ predicted by the
LH model can generate significant contributions to single top production via
the s-channel process. The correction terms for the tree-level $Wqq'$ couplings
coming from the SU(3) simple group model can give large contributions to the
cross sections of the t-channel single top production process. We expect that
the effects of the LH model and the SU(3) simple group model on single top
production can be detected at the LHC experiments.
