Triple Higgs boson production in the linear collider

We investigate the Higgs boson production processes [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] in the littlest Higgs model with T-parity (LHT) at the International Linear Collider (ILC). We calculate the LHT model predictions on the production rate of these processes at the ILC in the case of (un)polarized beams and the signal strengths of the production processes [Formula: see text] and [Formula: see text] with Higgs decaying to [Formula: see text]. In the allowed parameter space, we find that the signal strengths [Formula: see text] is most likely approach to the expected precision of the ILC.

Production Processes

In the framework of the minimal [Formula: see text] extension of the Standard Model, we investigate the Higgs boson production processes [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] at the International Linear Collider (ILC). We present the production cross-sections, the relative corrections and compare our results with the expected experimental accuracies for Higgs decay channel [Formula: see text]. In the allowed parameter space, we find that the effects of the three single Higgs boson production processes might approach the observable threshold of the ILC. But the Higgs signal strengths [Formula: see text] of the two double Higgs boson production processes are all out of the observable threshold so that these effects will be difficult to be observed at the ILC.

We have investigated the potential of Higgs boson production at [Formula: see text] mode of the Compact Linear Collider (CLIC) to probe anomalous ZZH couplings. Considering two different center of mass energies of CLIC ([Formula: see text] = 1.5 and 3 TeV) and various integrated luminosities, we have calculated 95% confidence level (CL) bounds on the anomalous ZZH coupling parameters [Formula: see text], [Formula: see text] and [Formula: see text]. We perform an analysis through the process [Formula: see text] with systematic uncertainties of [Formula: see text] = 0%, 5%, 10%. Obtained results have been discussed in terms of capability to probe anomalous ZZH couplings in the photoproduction process.
