A μ-τ-philic scalar doublet under Z_n flavor symmetry Reviewed

2019 ( 6 ) 2019.6

　More details

Language：English Publishing type：Research paper (scientific journal)

We propose a minimal model which accommodates the long-standing anomaly of muon magnetic moment based on abelian discrete flavor symmetries. The standard model is extended by scalar doublets charged under a Z_n lepton flavor symmetry. In these models, a large contribution to the muon magnetic moment can be obtained by the chirality enhancement from new scalar mediated diagrams without conflicting with the flavor symmetry. Thanks to the lepton flavor symmetry, these models automatically forbid lepton flavor violation. The minimal model is based on Z₄ symmetry with only one extra scalar doublet. In this model, we show that the parameter space favored by the muon g − 2 can easily be consistent with experimental constraints and theoretical bounds such as the electroweak precision tests, lepton universality, potential stability condition and triviality bound as well as the LHC direct search mass bound. The new contributions to the muon electric dipole moment and the Higgs decay into γγ can be indirect signals of the model.

2018 ( 12 ) 2018.12

　More details

Language：English Publishing type：Research paper (scientific journal)

The present work introduces two possible extensions of the Standard Model Higgs sector. In the first case, the Zee-Babu type model for the generation of neutrino mass is augmented with a scalar triplet and additional singly charged scalar singlets. The second scenario, on the other hand, generalizes the Type-II seesaw model by replicating the number of the scalar triplets. A ℤ₃ symmetry is imposed in case of both the scenarios, but, allowed to be violated by terms of mass dimension two and three for generating neutrino masses and mixings. We examine how the models so introduced can explain the experimental observation on the muon anomalous magnetic moment. We estimate the two-loop contribution to neutrino mass induced by the scalar triplet, in addition to what comes from the doubly charged singlet in the usual Zee-Babu framework, in the first model. On the other hand, the neutrino mass arises in the usual Type-II fashion in the second model. In addition, the role of the ℤ₃ symmetry in suppressing lepton flavor violation is also elucidated.

Determination of tanâ¡β from the Higgs boson decay at linear colliders Reviewed

88 ( 5 ) 2013.9

　More details

Language：English Publishing type：Research paper (scientific journal)

In the two Higgs doublet models, tanâ¡β is an important parameter, which is defined as the ratio of the vacuum expectation values of the doublets. We study how accurately tanâ¡β can be determined at linear colliders via the precision measurement of the decay branching fraction of the standard model (SM)-like Higgs boson. Since the effective coupling constants of the Higgs boson with the weak gauge bosons are expected to be measured accurately, the branching ratios can be precisely determined. Consequently, tanâ¡β can be determined with a certain amount of accuracy. Comparing the method to those using direct production of the additional Higgs bosons, we find that, depending on the type of Yukawa interactions, the precision measurement of the decay of the SM-like Higgs boson can be the best way to determine tanâ¡β, when the deviations in the coupling constants with the gauge boson from the SM prediction are observed at linear colliders.

Discrimination of models including H ^±± by using tau decay Reviewed

49 2013.9

　More details

Language：English Publishing type：Research paper (scientific journal)

The doubly charged scalar boson (H^±±) is introduced in several models of the new physics beyond the standard model. 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].

Multi-τ signatures at the LHC in the two Higgs doublet model Reviewed

85 ( 9 ) 2012.5

　More details

Language：English Publishing type：Research paper (scientific journal)

A detailed simulation study is performed for multi-τ signatures at the Large Hadron Collider, which can be used to probe additional Higgs bosons with lepton-specific Yukawa interactions. We here consider the two Higgs doublet model with the Type-X Yukawa interaction, where nonstandard Higgs bosons predominantly decay into tau leptons. These extra Higgs bosons can be pair produced at hadron colliders. Consequently, multi-τ originated signals appear in the final state as a promising signature of such a model. We find that the main background can be considerably reduced by requiring the high multiplicity of leptons and tau-jets with appropriate kinematical cuts in the final state. Thus, assuming the integrated luminosity of a hundred of inverse fb, the excess can be seen in various three- and four-lepton channels. With the integrated luminosity of thousands of inverse fb, the determination of the mass as well as ratios of leptonic decay branching ratios of these Higgs bosons would also be possible.

Higgs quadruplet for the type III seesaw model and implications for μ→eγ and μ-e conversion Reviewed

84 ( 7 ) 2011.10

　More details

Language：English Publishing type：Research paper (scientific journal)

In the type III seesaw model, the heavy neutrinos are contained in leptonic triplet representations. The Yukawa couplings of the triplet fermion and the left-handed neutrinos with the doublet Higgs field produce the Dirac mass terms. Together with the Majorana masses for the leptonic triplets, the light neutrinos obtain nonzero seesaw masses. We point out that it is also possible to have a quadruplet Higgs field to produce the Dirac mass terms to facilitate the seesaw mechanism. The vacuum expectation value of the quadruplet Higgs is constrained to be small by electroweak precision data. Therefore, the Yukawa couplings of a quadruplet can be much larger than those for a doublet. We also find that unlike the usual type III seesaw model where at least two copies of leptonic triplets are needed, with both doublet and quadruplet Higgs representations, just one leptonic triplet is possible to have a phenomenologically acceptable model because light neutrino masses can receive sizable contributions at both tree and one-loop levels. Large Yukawa couplings of the quadruplet can induce observable effects for lepton flavor violating processes μ→eγ and μ-e conversion. Implications of the recent μ→eγ limit from MEG and the limit on μ-e conversion on Au are also given. Some interesting collider signatures for the doubly charged Higgs boson in the quadruplet are discussed.

We compare constraints obtained from μ-e conversion using experimental bounds on various nuclei with those from μ→eγ and μ→eēe. We find that the current bound from μ-e conversion with Au puts the most stringent constraint in this model. The relevant flavor changing parameter λ_;μe=V^*4_μVe4 is constrained to be less than 1.6×10^-5 for the fourth generation neutrino mass larger than 100 GeV. Implications for future μ-e conversion, μ→eγ and μ→eēe experiments are discussed.

ν-Two Higgs doublet model and its collider phenomenology Reviewed

Language：English Publishing type：Research paper (scientific journal)

Smallness of neutrino masses can be explained by introducing a tiny vacuum expectation value of an extra-Higgs doublet which couples to right-handed neutrinos (NR). This situation is naturally realized in ν-Two Higgs Doublet Model (νTHDM), where a TeV-scale seesaw mechanism can work well. We investigate observable phenomenology of νTHDM at LHC and ILC experiments. Charged Higgs boson (H^±) in νTHDM is almost originated from the extra-Higgs doublet and its coupling strength to neutrinos are not small. Then this model induces rich phenomenology at the LHC, for example, when m _H^± > MN, observable charged tracks can be induced from long lived charged Higgs. On the other hand, when mH ^± < MN, right-handed neutrinos can be long-lived, and secondary vertices may be tagged at the LHC. The νTHDM also predicts observable lepton number violating process at the ILC.

　More details

Event date： 2012.11

Language：English

Venue：Kyoto Country：Japan

The doubly charged scalar boson (H^±±) is introduced in several models of the new physics beyond the standard model. 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].
