On Measuring $CP$ Violation in Neutral $B$-meson Decays at the ${\rm Y}(4S)$ Resonance

H. Fritzsch, D. Wu, Z. Xing

Within the standard model we carry out an analysis of $CP$-violating observables in neutral $B$-meson decays at the ${\rm Y}(4S)$ resonance. Both time-dependent and time-integrated $CP$…
