“…The light scalar φ 0 can also be produced associated with the SM-like Higgs h at the International Linear Collider (ILC), which has been studied in Ref. [73]. The numerical results show that the resonance production cross section can be significantly enhanced at the high energy linear collider with √ s ≃ m Z H .…”

In this paper we study the production and decays of a light pseudoscalar boson φ 0 with m φ 0 ≤ m h /2 appeared in the left-right twin Higgs (LRTH) model, and explore its phenomenological consequences when the latest LHC Higgs data are taken into account. We found that (a) the decay rate Br(h → φ 0 φ 0 ) can be as large as 80% and can suppress significantly the visible γγ signal rate, but the latest LHC Higgs data put a strong constraint on it: Br(h → φ 0 φ 0 ) ≤ 30% at 3σ level; (b) the p-value of the LRTH model is around 0.6, smaller than that of the SM in most of the parameter space and approaches the SM value 0.8 for a sufficiently large f parameter; (c) the neutral pseudoscalar φ 0 dominantly decay into bb and the decay rate Br(φ 0 → bb) can be larger than 80% for m φ 0 ≤ 60 GeV, and the second main decay mode is φ 0 → τ + τ − with a branching ratio about 14%; and (d) at the future e − e + collider with √ s = 250 GeV, the processes e + e − → Zh → Z(φ 0 φ 0 ) → Z(4b, 2b2τ ) are promising for discovering such a light pseudoscalar φ 0 .

“…In Ref. [64] the pair production of hφ 0 has been calculated in the LRTH. The cross sections are marginal and even close to threshold not larger than one fb, but can give rise to Z ′ resonances at CLIC in the range above 1 TeV.…”

In the framework of the Left-Right twin Higgs (LRTH) model, we consider the constrains from the latest search for high-mass dilepton resonances at the LHC and find that the heavy neutral boson Z H is excluded with mass below 2.76 TeV. Under these constrains, we study the Higgs-Gauge coupling production processes e + e − → ZH , e + e − → ν eνe H and e + e − → e + e − H , top quark Yukawa coupling production process e + e − → ttH , Higgs self-couplings production processes e + e − → ZH H and e + e − → ν eνe H H at e + e − colliders. Besides, we study the major decay modes of the Higgs boson, namely h → ff (f = b, c, τ ), V V * (V = W, Z), gg, γ γ . We find that the LRTH effects are sizable so that the Higgs boson processes at e + e − collider can be a sensitive probe for the LRTH model.
