Abstract
In this paper we study CP violation in the B ! PP decays in the Standard Model using
SU(3)
avor symmetry. With SU(3) symmetry, only seven hadronic parameters are needed
to describe the B ! PP decays in the SM, when annihilation contributions are neglected.
The relevant hadronic parameters can be determined using known experimental data from
B ! and B ! K. We predict branching ratios and CP asymmetries for some of the
unmeasured B ! PP decays. Some of the CP asymmetries can be large and measured at B
factories. The eects of the annihilation contributions can also be studied using the present
experimental data. Inclusion of annihilation contributions introduces six more hadronic
parameters. We nd that the annihilation contributions are in general small, but can have
signicant eects on CP asymmetries and some Bs ! PP decays.
