In one of our previous papers,we provided general,effective Higgs interactions for the lightest Higgs boson h（SM-like） and a heavier neutral Higgs boson H based on the effective Lagrangian formulation up to the dim-6 interactions,and then proposed two sensitive processes for probing H.We showed in several examples that the resonance peak of H and its dim-6 effective coupling constants（ECC） can be detected at LHC Run 2 with reasonable integrated luminosity.In this paper,we further perform a more thorough study of the most sensitive process,pp →VH^＊→VVV,providing information about the relations between the 1σ,3σ,5σ statistical significance and the corresponding ranges of the Higgs ECC for an integrated luminosity of 100 fb^-1.These results have two useful applications in LHC Run 2：（A） realizing the experimental determination of the ECC in the dim-6 interactions if H is found and,（B） obtaining the theoretical exclusion bounds if H is not found.Some alternative processes sensitive for certain ranges of the ECC are also analyzed.
