| 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 determine 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 not be probed via the H++ decays.
