On measuring CP violation in neutral B-meson decays at the $\Upsilon$ (4S) resonance

Within the standard model we carry out an analysis of CP-violating observables in neutral B-meson decays at the \Upsilon (4S) resonance. Both time-dependent and time-integrated CP asymmetries are calculated, without special approximations, to meet various possible measurements at symmetric and asymmetric e^{+}e^{-} B factories. We show two ways to distinguish between direct and indirect CP-violating effects in the CP-eigenstate channels such as B^{0}_{d}/\bar{B}^{0}_{d}\rightarrow \pi^{+}\pi^{-} and \pi^{0} K_{S}. Reliable knowledge of the Cabibbo-Kobayashi-Maskawa phase and angles can in principle be extracted from measurements of some non-CP-eigenstate channels, e.g. B^{0}_{d}/\bar{B}^{0}_{d}\rig htarrow D^{\pm}\pi^{\mp} and \stackrel{(-)}{D}^{(*)0}K_{S}, even in the presence of significant final-state interactions.
