Testing anomalous gauge couplings of the Higgs boson via weak-boson scatterings at the LHC

We propose a sensitive way to test the anomalous HVV couplings (V = W-+/-,W- Z(0)) of the Higgs boson (H), which can arise from the dimension-6 effective operators in a linearly realized Higgs sector, via studying the VV scattering processes at the CERN LHC. The gold-plated pure leptonic decay modes of the final state weak bosons in the processes pp -> VVjj are studied. We show that, with an integrated luminosity of 300 fb(-1) and sufficient kinematical cuts for suppressing the backgrounds, studying the process pp -> W(+)W(+)jj -> l(+)vl(+)vjj can probe the anomalous HWW couplings at the level of 0.01 - 0.08 TeV-1 for the linearly realized effective Lagrangian.
