Probing Z - Z` mixing at future e{sup +}e{sup -} colliders

Technical Report:

Abstract

We discuss the possibility of obtaining constrains on Z - Z` mixing from studies of the process e{sup +}e{sup -} {yields} W{sup +}W{sup -} at planned high energy e{sup +}e{sup -} colliders, and derive the corresponding limits on the Z` mass for different extended models. Our results indicate that the limits on the mixing angle are quite stringent, and can typically reach the level of 10{sup -5} - 10{sup -6}. We also present a detailed comparison with the potential of the reaction e{sup +}e{sup -} {yields} ff-bar which shows that significantly better sensitivity to Z - Z` mixing should be expected from W{sup +}W{sup -} production.
