We report a measurement of time-dependent $CP$ violation parameters in ${B^0 to K_S^0 eta gamma}$ decays. The study is based on a data sample, containing ${772 times 10^6 Bbar{B}}$ pairs, that was collected at the $Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider. We obtain the $CP$ violation parameters of ${{cal S} = -1.32 pm 0.77 {rm (stat.)} pm 0.36{rm (syst.)}}$ and ${{cal A} = -0.48 pm 0.41 {rm (stat.)} pm 0.07{rm (syst.)}}$ for the invariant mass of the $K_S^0 eta$ system up to 2.1 GeV/$c^2$.
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 $times 10^6$ $Bbar{B}$ pairs collected at the $Upsilon(4S)$ resonance with the Belle detect
We report measurements of CP violation parameters in $B^0 to K^0 pi^0$ decays based on a data sample of $657 times 10^6 Bbar{B}$ pairs collected with the Belle detector at the KEKB $e^+ e^-$ asymmetric-energy collider. We use $B^0 to K^0_S pi^0$ deca
We report improved measurements of time-dependent CP violation parameters for B^0(bar{B}^0) -> psi(2S) K_S. This analysis is based on a data sample of 657x10^6 BBbar pairs collected at the Y(4S) resonance with the Belle detector at the KEKB energy-as
We report a measurement of time-dependent $CP$ violation in $B^0 to K^0_S pi^0 pi^0$ decays using a data sample of $772 times 10^6$ $Bbar{B}$ pairs collected by the Belle experiment runnin g at the $Upsilon (4S)$ resonance at the KEKB $e^+ e^-$ colli
We present a measurement of the time-dependent $CP$ violation parameters in $B^0toetaK^0$ decays. The measurement is based on the full data sample containing $772times 10^6$ $Bbar{B}$ pairs collected at the $Upsilon(4S)$ resonance using the Belle det
