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…
