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

TL;DR

This paper investigates the production of neutral Higgs boson pairs within the left-right twin Higgs model at the ILC and LHC, highlighting potential experimental signatures for testing the model.

Contribution

It provides the first detailed analysis of neutral Higgs pair production cross sections in the left-right twin Higgs model at both colliders.

Findings

Cross sections of several tens fb at ILC for e+e- to phi^0 h.

Cross sections of several hundreds fb at LHC for phi^0 phi^0 and phi^0 h.

Potential to test the model if neutral Higgs bosons are not too heavy.

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 $e^{+}e^{-}\to \phi^{0}h$ are at the level of several tens $fb$ at the $ILC$, the production cross section of the $\phi^{0}\phi^{0}$ pair and $\phi^{0}h$ pair are at the level of several hundreds $fb$ at the $LHC$. As long as the neutral Higgs boson $\phi^{0}$ 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.
