We first formulate, in the framework of effective Lagrangian, the generalform of the effective interactions of the lightest Higgs boson h and a heavierneutral Higgs boson H in a multi-Higgs system taking account of Higgs mixingeffect. We regard h as the discovered Higgs boson which has been shown to beconsistent with the standard model (SM) Higgs boson. The obtained effectiveinteractions contain extra parameters reflecting the Higgs mixing effect. Next,We study the constraints on the anomalous coupling constants of H from both therequirement of the unitarity of the S matrix and the exclusion bounds on the SMHiggs boson obtained from the experimental data at the 7--8 TeV LHC. From thiswe obtain the available range of the anomalous coupling constants of H, withwhich H is not excluded by the yet known theoretical and experimentalconstraints. We then study the signatures of H at the 14 TeV LHC. In thispaper, we suggest taking weak-boson scattering and pp to VH* to VVV assensitive processes for probing H model independently at the 14 TeV LHC. Wetake several examples with the anomalous HVV coupling constants in theavailable ranges to do the numerical study. a full tree-level calculation atthe hadron level is given with signals and backgrounds carefully calculated. Weimpose a series of proper kinematic cuts to effectively suppress thebackgrounds. It is shown that, in both the VV scattering and the pp to VH* toVVV processes, H boson can be discovered from the invariant mass distributionsof the final state particles with reasonable integrated luminosity. Especially,in the pp to VH* to VVV process, the invariant mass distribution of the finalstate jets can show a clear resonance peak of H. Finally, we propose severalphysical observables from which the values of the anomalous coupling constantsf_W and f_{WW} can be measured experimentally.
