Effect of inelastic scalar dark matter in hidden scenario after the LZ nuclear recoil
Arindam Das, Takaaki Nomura
We study a hidden extension of the Standard Model (SM) introducing two SM singlet complex scalar fields where one of them can be considered as a viable inelastic Dark Matt…
Are 2HDMs with a gauged symmetry alive?
Yuanchao Lou, Takaaki Nomura, Xinran Xu +1
We investigate the phenomenology of 2 Higgs doublet models (2HDMs) with a new gauge symmetry, , by which flavor changing neutral currents are forbidden at tree level…
Lepton number violation from Higgs/ decays into a pair of right-handed neutrinos
Arindam Das, Takaaki Nomura, Kei Yagyu
We explore signatures of Lepton Number Violation (LNV) from decays of the discovered Higgs () and Z bosons into a pair of Right-Handed Neutrinos (RHNs). Due to the Majorana natu…
New Physics Search at the CEPC: a General Perspective
Xiaocong Ai, Stefan Antusch, Peter Athron +211
The Circular Electron-Positron Collider (CEPC), a proposed next-generation Higgs factory, provides new opportunities to explore physics beyond the Standard Model (SM). With its cle…
Multi-Lepton Jets from Quadruple via the Higgs Decay at LHC
Jinmian Li, Takaaki Nomura, Kei Yagyu
We investigate multi-lepton jet events from the decay of the 125 GeV Higgs boson () into quadruple new gauge bosons at the LHC. Such an exotic decay is realized via the p…
Triple signatures at factories
Takaaki Nomura, Kei Yagyu
We discuss triple boson signatures via the decay chain of , with a new light scalar , at future Z factories such as CEPC and FCC-ee. These new boson…
Testing tree level TeV scale seesaw scenarios in TRISTAN
Arindam Das, Jinmian Li, Sanjoy Mandal +2
We investigate TeV scale seesaw scenarios at and colliders in the TRISTAN experiment. In minimal type-I seesaw scenario we consider two generations of Standa…
Multi- signatures of spontaneously broken local symmetry
Takaaki Nomura, Kei Yagyu
We discuss multi- signatures coming from decays of Higgs bosons in models with a spontaneously broken symmetry, which can be observed as "lepton jets" or multi-lepton f…
Neutrino observables in gauged models with two Higgs doublet and one singlet scalars
Yuanchao Lou, Takaaki Nomura
We discuss neutrino sector in models with two Higgs doublet and one singlet scalar fields under local symmetry. A neutrino mass matrix is formulated for these mod…
Search for pair production from scalar boson decay in minimal model at the LHC
Takaaki Nomura, Takashi Shimomura
We consider a model with gauged symmetry in which the symmetry is spontaneously broken by a scalar field. The decay of the scalar boson into two new gauge bosons is stud…
