The 750 GeV diphoton excess and its explanation in 2-Higgs Doublet Models with a real inert scalar multiplet
Stefano Moretti, Kei Yagyu
We discuss a possible explanation of the recently observed diphoton excess at around 750 GeV as seen by the ATLAS and CMS experiments at the Large Hadron Collider. We calculate the…
Radiative corrections to the Higgs boson couplings in the model with an additional real singlet scalar field
Shinya Kanemura, Mariko Kikuchi, Kei Yagyu
We calculate renormalized Higgs boson couplings with gauge bosons and fermions at the one-loop level in the model with an additional isospin singlet real scalar field. These coupli…
Higgs Triplet Model with Classically Conformal Invariance
Hiroshi Okada, Yuta Orikasa, Kei Yagyu
We discuss an extension of the minimal Higgs triplet model with a classically conformal invariance and with a gauged symmetry. In our scenario, tiny masses of neutrino…
Phenomenology of the Georgi-Machacek model at future electron-positron colliders
Cheng-Wei Chiang, Shinya Kanemura, Kei Yagyu
We study the phenomenology of the exotic Higgs bosons in the Georgi-Machacek model at future electron-positron colliders such as the International Linear Collider (ILC), assuming t…
CP Violating Two-Higgs-Doublet Model: Constraints and LHC Predictions
Venus Keus, Stephen F. King, Stefano Moretti +1
Two-Higgs-Doublet Models (2HDMs) are amongst the simplest extensions of the Standard Model. Such models allow for tree-level CP Violation (CPV) in the Higgs sector. We analyse a cl…
Unitarity bound in the most general two Higgs doublet model
Shinya Kanemura, Kei Yagyu
We investigate unitarity bounds in the most general two Higgs doublet model without a discrete symmetry nor CP conservation. S-wave amplitudes for two-body elastic scattering…
