Study of CP Violation in Flavor Tagged and Untagged $D^{0} \to K^{-} π^{+}$ Decays

E. Won, B. R. Ko, B. Golob

We review $C P$ -violating observables in flavor tagged and untagged $D^{0} \to K^{-} π^{+}$ decays and evaluate the $C P$ asymmetry difference between the two decays. We note th…

Measurement of Time-Dependent $C P$ Violation in $B^{0} \to η^{'} K^{0}$ Decays

Belle Collaboration, L. Šantelj, Y. Yusa +163

We present a measurement of the time-dependent $C P$ violation parameters in $B^{0} \to η^{'} K^{0}$ decays. The measurement is based on the full data sample containing $772 \times 1 0^{6}$ $B\ba…

Updated Cross Section Measurement of $e^{+} e^{-} \to K^{+} K^{-} J / ψ$ and $K_{S}^{0} K_{S}^{0} J / ψ$ via Initial State Radiation at Belle

Belle Collaboration, C. P. Shen, C. Z. Yuan +159

The cross sections of the processes $e^{+} e^{-} \to K^{+} K^{-} J / ψ$ and $K_{S}^{0} K_{S}^{0} J / ψ$ are measured via initial state radiation at center-of-mass energies between the threshold and 6.0~…
