Some comments on B -> pi pi decays
Abstract
Description
Isospin analysis has been used to constrain the CP-asymmetries in B -> pi pi decays. In particular correlation between a weak phase θand a strong phase δis obtained. Further using the experimental values for the CP-average branching ratios, the following bounds on direct CP-asymmetries are obtained: -0.35+/- 0.22=< C_{π^+π^-}\leq 0; C_{π^0π^0}=-(2.4\pm 1.0) C_{π^+π^-}. Constraints on mixing induced CP-asymmetries are also discussed.
