摘要：

We examine various direct and indirect constraints on the lepton-specific two-Higgs-doublet model and scrutinize the property of the Higgs bosons in the allowed parameter space. We find that in the allowed parameter space the CP-odd Higgs boson A is rather light (m(A) < 30 GeV with 95% possibility), which is composed dominantly by the leptonic Higgs and decays dominantly into tau(+) tau(-); while the standard-model-like Higgs boson h (responsible largely for electroweak symmetry breaking) decays dominantly in the mode h -> AA -> 4 tau with a large decay width, which will make the Higgs discovery more difficult at the LHC, whereas this scenario predicts a branching ratio Br(Z -> tau(+) tau(-) A) ranging from 10(-5) to 10(-4), which may be accessible at the GigaZ option of the International Linear Collider.
