Abstract
We discuss various CP violation effects of neutral B mesons within the framework of the standard model. We classify 28 hadronic two-body decay channels of neutral B mesons into four classes, each of them has different CP violation effects, that is, CP violation due to phase difference between mixing elements M12 and Γ12; due to that between mixing elements and decay amplitudes; due to CP phase in the pure particle decay amplitudes and the interplay of these sources .Cascade decays of these channels are also discussed where copious interference is taken into account. Results are given in rephasing invariants of the K-M matrix. It is shown that CP violation effects might be large (the largest, 10-1, but the CP asymmetry event branching cross section is small, at the order or approximate .
