Measurement of Branching Fraction and Search for $CP$ Violation in $B\to ����K$

We report the measurement of branching fractions and $CP$-violation asymmetries in $B\to ����K$ decays based on a $711\,{\rm fb}^{-1}$ data sample containing $772\times 10^6$ $B\bar{B}$ events. The data were recorded at the $��(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider. For $B^+ \to ����K^+$, the branching fraction and $CP$-violation asymmetry measured below the $��_{c}$ threshold ($m_{����}
