The form of the mixing matrix of quarks is discussed. The exponential parameterisation of the Cabibbo-Kobayashi-Maskawa (CKM) matrix is identified as the most general form of the mixing matrix. Its properties are reviewed in the context of the unitarity requirement. A recurrence series representation of the exponential form of the mixing matrix that is easy to handle is obtained, allowing for a direct and simple method of calculation of the CKM matrix. The generation of the new parameterisations of the CKM matrix by the exponential form is demonstrated. © Springer-Verlag Berlin Heidelberg 2007.
