Abstract
Several methods proposed to measure the angle γ in the KM unitarity triangle assumed that the tree contribution to B- → π-K̄0 is purely due to annihilation contributions and is negligibly small. This assumption has to be tested in order to have a correct interpretation of the experimental data. In this paper we show that using SU(3) symmetry, the smallness of the tree contribution can be tested in a dynamic model-independent way. We also derive several relations between CP violating rate differences for B → PP decays without assuming the smallness of the annihilation contributions. These relations provide important tests for the standard model of CP violation.
