Interpreting the time-dependent CP asymmetry in B0→ π0KS
Abstract
Flavor SU(3) is used for studying the time-dependent CP asymmetry in B0→π0KS by relating this process to B0→π0π0 and B0→K+K-. We calculate correlated bounds on SπK-sin2β and CπK, with maximal magnitudes of 0.2 and 0.3, where SπK and CπK are coefficients of sinΔmt and cosΔmt in the asymmetry. Stronger upper limits on B0→K+K- are expected to reduce these bounds and to imply nonzero lower limits on these observables. The asymmetry is studied as a function of a strong phase and the weak phase γ.
