Terahertz spectroscopy of NO and isotopic invariant fit of several nitric oxide isotopologs
Holger S. P. Müller, Kaori Kobayashi, Kazumasa Takahashi +2
A tunable far-infrared laser sideband spectrometer was used to investigate a nitric oxide sample enriched in 18O between 0.99 and 4.75 THz. Regular, electric dipole transitions wer…
LHC Run-I constraint on the mass of doubly charged Higgs bosons in the same-sign diboson decay scenario
Shinya Kanemura, Mariko Kikuchi, Kei Yagyu +1
In this Letter, we study the latest bound on the mass of doubly charged Higgs bosons, , assuming that they dominantly decay into a diboson. The new bound is obtained by…
Radiative corrections to Higgs coupling constants in two Higgs doublet models
Mariko Kikuchi
A pattern of deviations in the Standard Model (SM) like Higgs boson () couplings from their SM predictions depends on the structure of the Higgs sector and the Yukawa interactio…
Higgs Phenomenology of the Supersymmetric Grand Unification with the Hosotani Mechanism
Mitsuru Kakizaki
The supersymmetric SU(5) grand unified theory with the gauge symmetry broken by the Hosotani mechanism naturally solves the mass hierarchy problem between the colored Higgs triplet…
New resonance scale and fingerprint identification in minimal composite Higgs models
Shinya Kanemura, Kunio Kaneta, Naoki Machida +1
Composite Higgs models are an intriguing scenario in which the Higgs particle is identified as a pseudo Nambu-Goldstone boson associated with spontaneous breaking of some global sy…
Bounds on the mass of doubly-charged Higgs bosons in the same-sign diboson decay scenario
Shinya Kanemura, Mariko Kikuchi, Kei Yagyu +1
A direct search for doubly-charged Higgs bosons is one of the most important probe in the Higgs Triplet Model, which is motivated by generation mechanisms of tiny neut…
