Abstract: (Elsevier)

We consider sensitivities on anomalous gauge and gauge-Higgs couplings in the process W + W at the LHC and the ILC. Within an effective Lagrangian approach we find that six anomalous couplings can be studied in this process using the normalised ev ent distributions. We employ optimal observables to disentangle the contributions from these six anomalous couplings. Preliminary results indicate that sensitivities in W + W at the LHC may be competitive with available results for certain gauge couplings and give direct access to two anomalous gauge-Higgs couplings. Measuring W + W with the photon mode of the ILC could improve the corresponding sensitivities by two orders of magnitude. Polarisation of the initial photons is a valuable tool to achieve ver y high precisions.
