Abstract
The twin Higgs mechanism has recently been proposed to solve the little hierarchy problem. In the context of the left-right twin Higgs (LRTH) model, we discuss single production of the new charged gauge boson WH−, which is predicted by the left-right twin Higgs model, in association with top quark at the CERN Large Hadron Collider (LHC). It is found that, for a typical nonzero value of mass mixing parameter M = 150 GeV in the LRTH model, the production cross section is in the range of 3 × 10-2 ∼ 6.07 × 103 fb at the LHC. As long as the WH− is not too heavy, the possible signatures of the heavy charged gauge boson might be detected at the LHC experiments.
