We study the anomalous trilinear gauge couplings of Z and using a complete set of polarization asymmetries for the Z boson in processes with unpolarized initial beams. We use these polarization asymmetries, along with the cross section, to obtain a simultaneous limit on all the anomalous couplings using the Markov Chain Monte Carlo (MCMC) method. For an collider running at 500 GeV center-of-mass energy and 100 fb of integrated luminosity the simultaneous limits on the anomalous couplings are 1–3.
