Abstract
We estimate model-independent bounds that could be obtained on the anomalous vertex using polarization parameters of the boson produced in the Higgstrahlung process at the LHC. We calculate the eight independent polarization parameters from the spin density matrix elements of the , which can probe underlying new physics contributions to production. By using the approach that connects these polarization observables to the coefficients in the angular distribution of the decay products of the , we estimate the limits on the anomalous coupling that can be obtained at the 14 TeV LHC.
