Measurements of time-dependent CP violation in $B^0\to \omega K_S^0$, $f_0(980)K_S^0$, $K_S^0{\pi }^0$ and $K^{+}{K}^{-}{K}_S^0$ decays

Abstract

We present measurements of time-dependent CP asymmetries in $B^0\to \omega K_S^0$, $f_0(980)K_S^0$, $K_S^0{\pi }^0$ and $K^{+}{K}^{-}{K}_S^0$ based on a sample of 535 $\times 10^6$ $B\bar{B}$ pairs collected at the ${\rm Y}(4S)$ resonance with the Belle detector at the KEKB energy-asymmetric $e^{+}{e}^{-}$ collider. One neutral $B$ meson is fully reconstructed in one of the specified decay channels, and the flavor of the accompanying $B$ meson is identified from its decay products. CP-violation parameters for each of the decay modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays.
