We discuss the impact of non-standard Higgs couplings at the LHC. Using a model-independent -effective Lagrangian- approach, we focus on pure Higgs and Higgs-gauge operators, assuming that the new physics scale is larger than the electroweak one. Present constraints and future signals are explored, for those anomalous couplings which may be generated by tree-level exchange of unknown heavy particles. On a second stage, the quantum numbers of those possible tree-level mediators are identified, leading to additional correlated new signals.
