In this paper, we calculated the supersymmetric contributions to the branching ratios and CP-violating asymmetries of the four B→Kπ decays in both the general and the constrained minimal supergravity (mSUGRA) model. Within the considered parameter space, we found that (a) the phase ϕμin the general mSUGRA model is strongly constrained by the data of the electron and neutron electric dipole moment and the data of B→Xsγ decay: ϕμ<0.1 (<10-3) for the case of small (large) tan β, but no limit on the phase ϕAcan be derived from the above data; (b) in both the general and the constrained mSUGRA model, the SUSY contributions are not large enough to explain the observed B→Kπ puzzle.
