We consider the momentum dependent effects in Higgs couplings generated by physics beyond the standard model. We take a model dependent approach, in which we can compute fully the non-local effects from physics not directly reachable by the LHC energy. We consider several scenarios, including composite Higgs models, additional scalars, and the continuum contributions of a quasi-conformal sector, as examples. For each specific model, we obtain the full form factor, with which one can eventually fully simulate the effects in kinematics distributions. The momentum dependent effects appear as a consequence of off-shellness in the process. We show how the sensitivity of different channels to the various models depends on the flow of off-shellness in the Higgs couplings.
