Abstract
Dighe, Gronau, and Rosner have shown that, by assuming SU(3) flavor symmetry and first-order SU(3) breaking, it is possible to extract the (Formula presented) angles α and γ from measurements of the decay rates of (Formula presented) (Formula presented) and (Formula presented) along with their charge-conjugate processes. We extend their analysis to include the SU(3)-related decays (Formula presented) (Formula presented) and (Formula presented) There are several advantages to this extension: discrete ambiguities are removed, fewer assumptions are necessary, and the method works even if all strong phases vanish. In addition, we show that γ can be obtained cleanly, with no penguin contamination, by using the two decays (Formula presented) and (Formula presented).
