Pair production of Higgs bosons associated with $Z$ boson in the left-right twin Higgs model at the ILC

Yao-Bei Liu, Xue-Lei Wang

The left-right twin Higgs(LRTH) model predicts the existence of three additional Higgs bosons: one neutral Higgs ${\varphi }^0$ and a pair of charged Higgs bosons ${\varphi }^{\pm }$. In this paper…
