-Two Higgs Doublet Model and its Collider Phenomenology
Smallness of neutrino masses can be explained by introducing a tiny vacuum
expectation value of an extra-Higgs doublet which couples to right-handed
neutrinos (). This situation is naturally realized in -Two Higgs
Doublet Model (THDM), where a TeV-scale seesaw mechanism can work well. We
investigate observable phenomenology of THDM at LHC and ILC experiments.
Charged Higgs boson () in THDM is almost originated from the
extra-Higgs doublet and its coupling strength to neutrinos are not small. Then
this model induces rich phenomenology at the LHC, for example, when
, observable charged tracks can be induced from long lived
charged Higgs. On the other hand, when , right-handed
neutrinos can be long-lived, and secondary vertices may be tagged at the LHC.
The THDM also predicts observable lepton number violating process at the
ILC.Comment: 17 pages, 27 eps file
