The anomalous trilinear gauge couplings of Z and are studied in with longitudinal beam polarizations using a complete set of polarization asymmetries for the Z boson. We quantify the goodness of the beam polarization in terms of the likelihood and find the best choice of and polarizations to be (, ), (, ) and (, ) for ZZ, and combined processes, respectively. Simultaneous limits on anomalous couplings are obtained for these choices of beam polarizations using Markov-Chain–Monte-Carlo (MCMC) for an collider running at GeV and fb. We find the simultaneous limits for these beam polarizations to be comparable with each other and also comparable with the unpolarized beam case.
