Description

After the discovery of the Higgs boson it became even more important to perform precision measurements and to search for deviations from the Standard Model predictions in the electroweak sector. A study of the measurement of trilinear gauge couplings is presented looking at the semi-leptonic W-pair production in e+e- annihilation at the ILC at centre-of-mass energies of 500 GeV and 1 TeV with polarized beams. It is based on a realistic full simulation of this process in the ILD detector at the ILC. We employed a maximum likelihood analysis of a three-dimensional differential cross section based on the W and W decay product angular distributions. A high sensitivity can be reached at the ILC that will allow to probe effects of new physics at the loop level.
