Testing origin of neutrino mass at the LHC

| Abstract: |
Neutrino mass is the first evidence for physics beyond Standard Model.
However, how neutrino mass arises still remains an open question. We
propose to make use of the upcoming LHC to test the type-II seesaw model.
The search mostly involves exotic Higgs search at LHC. By identifying the
flavor structure of the lepton number violating decays of the charged
Higgs bosons, one can establish the neutrino mass pattern of the Normal
Hierarchy, Inverted Hierarchy or Quasi-Degenerate. The associated pair
production of H++H- is essential to test the triplet nature of the Higgs
field. The observation of either H+ --> tau+ nubar or H+ --> e+ nubar will
be particularly robust for the test since they are independent of the
unknown Majorana phases, which could be probed via the H++ decays.
