Unitarity violation of the CKM matrix in a nonuniversal gauge interaction model
Kang Young Lee
Abstract
We explore the unitarity violation of the CKM matrix in the model in which the third generation fermions are subjected to the separate SU(2)L gauge interaction. With the recent LEP and SLC data at Z-pole and low-energy neutral current interaction data, the analysis on the parameter space of the model is updated, and the unitary violation is predicted under the constraint.
