Unified Parametrization of Quark and Lepton Mixing Matrices

Abstract

We present a unified parametrization of quark and lepton mixing matrices. By using some simple relations between the mixing angles of quarks and leptons, i.e., the quark-lepton complementarity, we parametrize the lepton mixing matrix with the Wolfenstein parameters $\lambda$ and $A$ of the quark mixing matrix. It is shown that the Wolfenstein parameter $\lambda$ can measure both the deviation of the quark mixing matrix from the unit matrix, and the deviation of the lepton mixing matrix from the exactly bimaximal mixing pattern.
