CP violation in $B \to \phi K$ decay and anomalous right-handed top quark couplings

Abstract

We explore the 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 the new CP violation and lead to a deviation of the observed weak phase in $B \to \phi K$ decays, which takes account for the present disagreement of the observed $\sin 2 \beta$ between $B \to J/\psi K$ and $B \to \phi K$ decays. The direct CP violation is also predicted.
