Abstract
We study the effects of the fourth quark generation model in Bd→ϕKS decay. With the up-to-date experimental data of Br (Bd → ϕKS), SϕKS and AϕKS, we derive the new bound of the new weak phase ϕsb, which is much more stringent than the existing one. At the same time, the theoretical predictions within the SM for Br (Bd → ϕKS), SϕKS and AϕKS agree with the current experimental data within errors.
