Pair production of neutral Higgs bosons from the left-right twin Higgs model at the ILC and LHC

Abstract

In the framework of the left-right twin Higgs model, we study pair production of the neutral Higgs bosons at the International Linear Collider (ILC) and the CERN LHC. We find that the production cross section of the process ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\phi}}^{0}h$ are at the level of several tens fb at the ILC, the production cross section of the ${\ensuremath{\phi}}^{0}{\ensuremath{\phi}}^{0}$ pair and ${\ensuremath{\phi}}^{0}h$ pair are at the level of several hundreds fb at the LHC. As long as the neutral Higgs boson ${\ensuremath{\phi}}^{0}$ is not too heavy, we conclude that its pair production might be used to test for the left-right twin Higgs model at the LHC experiment or in the future ILC experiment.
