ILC Sensitivity on Generic New Physics in Quartic Gauge Couplings

We investigate the potential of the ILC for measuring anomalous quartic gauge couplings, both in production of three electroweak gauge bosons as well as in vector boson scattering. Any new physics that could possibly couple to the electroweak gauge bosons is classified according to its spin and isospin quantum numbers and parameterized in terms of resonance parameters like masses, widths, magnetic moment form factors etc. By a maximum log-likelihood fit, the discovery reach of a 1 TeV ILC for scalar, vector and tensor resonances is examined.
