Abstract
The decay modes B to ππ, ψKS, K-D, πK, and ηK are promising channels to study the unitarity triangle of the CP-violating Cabibbo-Kobayashi-Maskawa (CKM) matrix. In this paper I study the consequences of these measurements in the Weinberg model. I show that using the same set of measurements, the following different mechanisms for CP violation can be distinguished: (1) CP is violated in the CKM sector only; (2) CP is violated spontaneously in the Higgs sector only; and (3) CP is violated in both the CKM and Higgs sectors. © 1996 The American Physical Society.
