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…
Inert Extension of the Zee-Babu Model
Hiroshi Okada, Takashi Toma, Kei Yagyu
We propose a two-loop induced Zee-Babu type neutrino mass model at the TeV scale. Although there is no dark matter candidate in the original Zee-Babu model, that is contained in ou…
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…
Novel Constraint on Parameter Space of the Georgi-Machacek Model by Current LHC Data
Cheng-Wei Chiang, Shinya Kanemura, Kei Yagyu
The same-sign diboson process has been measured at the LHC using leptonic decay channels of the bosons, with production cross sections of two fiducial re…
Fingerprinting non-minimal Higgs sectors
Shinya Kanemura, Koji Tsumura, Kei Yagyu +1
After the discovery of the standard-model-like Higgs boson at the LHC, the structure of the Higgs sector remains unknown. We discuss how it can be determined by the combination of…
Doubly-charged Higgs bosons in the diboson decay scenario at the ILC
Kei Yagyu
The Higgs Triplet Model (HTM) is one of important examples for extended Higgs sectors, because tiny neutrino masses can be simply explained. Unlike the canonical type-I seesaw mode…
