Abstract

We calculate the

CP

asymmetry in the penguin-dominated inclusive quark subprocess

b \to s φ

. This calculation should be valid for all two-body processes, such as

B \to K φ

B \to K^{*} φ

, which are penguin dominated. The asymmetry is less than one percent in the three-generation model, but could be as large as 20% in the four-generation model.
