The quark mixing matrix with manifest Cabibbo substructure and an angle of the unitarity triangle as one of its parameters

The quark mixing matrix is parameterised such that its Cabibbo substructure is emphasised. One can choose one of the parameters to be an arbitrarily chosen angle of the unitarity triangle, for example, the angle beta (also called Phi(1)) (c) 2005 Elsevier B.V. All rights reserved.
