Supersymmetric contributions to B ---> K pi branching ratio

(eng) We analyze the supersymmetric contributions to the B --> K\pi process. We show that the simultaneous contributions from the penguin diagrams with chargino and gluino in the loop could lead to a possible solution to the B --> K \pi puzzle. Our result indicates that including the stringent constraint from the b --> s \gamma branching ratio, the supersymmeteric models with light right-handed top-squark and large mixing between second and third generation of up and down squarks is the most preferred by the current experimental data.
