The discovery of the Higgs boson marks the beginning of the direct study of the electroweak symmetry breaking sector. The couplings of the new state can be studied using effective lagrangians to parametrize the deviations with respect to the standard model expectations. As it is well known effective lagrangian can lead to unitarity breakdown at high energies. In this project we will study unitarization mechanisms in order to render the calculations for LHC processes meaningful. (AU)
