The H±± can have Yukawa interactions with two left-handed charged leptons or two righthanded charged leptons. We study kinematical properties of H±± decay products through tau leptons in order to discriminate the chiral structures of the new Yukawa interaction. The chirality of tau leptons can be measured by the energy distributions of the tau decay products, and thus the chiral structure of the new Yukawa interaction can be traced in the invariant-mass distributions of the H ±± decay products [1].. |

In the THDM-X, new Higgs bosons mostly decay into tau leptons in the wide range of the parameter space. Such scalar bosons are less constrained by current experimental data, because of the suppressed quark Yukawa interactions. We discuss a search strategy of the THDM-X with multi-tau lepton final states at International linear collider and Large Hadron Collider. By using the collinear approximation, we show that a four tau lepton signature (e+e- → HA → 4τ ) can be a clean signal.. |

We focus on the scenario in which the lightest Higgs boson has the standard model like couplings to gauge bosons. We take into account the one-loop correction to the hhh coupling as well as additional one-loop diagrams due to charged bosons to the γγ → hh helicity amplitudes. We discuss the impact of these corrections on the hhh coupling measurement at the Photon Linear Collider.. |
| 151. | Shinya Kanemura, Koji Tsumura, Measuring Higgs boson associated Lepton Flavour Violation in electron-photon collisions at the ILC, 8th General Meeting of the ILC Physics Working Group, 2009.12, We study the LFV Higgs production processes e-γ → l- φ (l = μ, τ; φ = H, A) as a probe of Higgs mediated LFV couplings at an electron-photon collider, where H and A are extra CP even and odd Higgs bosons, respectively, in the two Higgs doublet model. Under the constraints from the current data of muon and tau rare decay, the cross section can be significantly large. It would improve the experimental upper bounds on the effective LFV coupling constants. In addition, the chirality nature of the LFV Higgs coupling constants can be measured by selecting electron beam polarizations.. |

We discuss the top quark anomalous couplings which can be described by higher dimensional operators. We investigate the process e-e+ → W-W+vv̄ → tt̄vv̄ to study the contribution of the anomalous top-Higgs coupling to the cross section. The effect of the dimension-six top-Higgs interaction on the cross section can be a few hundred percent greater than the SM prediction. Such a large effect can be measured at the International Linear Collider.. |

Tsumura, Measurement of lepton flavor violating yukawa couplings at ILC, 2005 International Linear Collider Workshop, LCWS 2005, 2005.12, We discuss lepton flavor violation (LFV) associated with tau leptons in the general framework of the two Higgs doublet model, in which LFV couplings are introduced as a deviation from Model II Yukawa interaction. Parameters of the model are constrained from experimental results and also from requirements of theoretical consistencies such as vacuum stability and perturbative unitarity. Current data for LFV rare tau decays provide substantial upper limits on the LFV Yukawa couplings in the large tanβ region, which are comparable with predictions in fundamental theories. Here tan β is the ratio of vacuum expectation values of the two Higgs doublets. A search for the LFV decays φ0→ τ±μ∓ (τ±e∓) of neutral Higgs bosons (φ0 = h, H and A) at future collider experiments can be useful to further constrain the LFV couplings, especially in the relatively small tanβ region (tan β ≲ 30), where rare tau decay data cannot give any strong limit.. |
