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…

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…

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…

Higgs Alignment from Multicritical-Point Principle in Two Higgs Doublet Models

Hikaru Kawai, Kiyoharu Kawana, Kin-ya Oda +1

In models with non-minimal Higgs sectors, enforcing (near) Higgs alignment, necessary to prevent significant deviations in the Higgs boson coupling from the standard model predicti…

Enhancement of the Higgs decay into a pair in models with gauge symmetry

ShivaSankar K. A., Arindam Das, Kei Yagyu

We discuss the Higgs phenomenology in models with a new gauge symmetry including the scenario, where three right-handed neutrinos are inevitably introduced du…
