Discrete Ambiguities In Extracting Weak Phases from B decays

الأصل · EN

Phases of elements of the Cabibbo-Kobayashi-Maskawa (CKM) matrix, as obtained using decays of B mesons to π+ π-, π± K∓, and π+ K⁰ or π- K⁰, are shown to have a class of discrete ambiguities. In most cases these can be eliminated using other information on CKM phases.
