In the left-right twin Higgs (LRTH) model, we first examine the effects on the production at the ILC and LHC. Our results show that in the allowed parameter space, the absolute values of the relative correction can be significantly large and thus provide a good test for the LRTH model. We also estimate the new production channel of or at the LHC and find that, with reasonable parameter values of the LRTH model, the values of the total hadronic cross-section can reach the level of 102 fb. The dominant decay mode , with (or h→W+W−) can make the processes give rise to the (or ) final state, which has less background than production, and thus this new channel may likely be observable at the LHC.
