Abstract

We explore CP violation in $B \to \phi K$ decay processes in the presence of the anomalous right-handed $\bar{t}sW$ and $\bar{t}bW$ couplings. The complex anomalous top coupling can be a source of new CP violation and may lead to a deviation of the observed weak phase in $B \to \phi K$ decays, which accounts for the present disagreement of the observed $\sin 2 \beta$ between $B \to J/\psi K$ and $B \to \phi K$ decays. Direct CP violation is also predicted.
