摘要：

Isospin relations are used to eliminate hadronic uncertainties in various CP asymmetries in B0 decays. In addition to the simple triangle relations for the pi-pi-mode, we study quadrilateral relations for K-pi and pentagon relations for rho-pi. A combined angular and isospin analysis is required for rho-rho. These methods are useful also for three-body decays such as K-pi-pi. The magnitude of the penguin amplitude can be extracted in various modes. The theoretical principles behind this analysis can be experimentally tested through sum rules for decay rates prior to the measurement of CP asymmetries.
