| dc.description | We present the new and updated $BABAR$ measurements of CP-violation studies for many $b\to s $ penguin decay modes. We report the first observation of mixing-induced CP-violation in $B^0 \to η^{'} K^0$ with a significance (including systematic uncertainties) of 5.5$σ$. We also present the first observation of the decay $B^0 \to ρ^0 K^0$. Using the time-dependent Dalitz plot analysis of $B^0\to K^+K^- K^0$ decay, the CP-parameters $\mathcal A_{CP}$ and $β_{eff}$ are measured with $4.8σ$ significance, and we reject the solution near $π/2 - β_{eff}$ at $4.5σ$. We also present the updated measurements of CP-violating parameters for $B^0 \to K_S^0 π^0$, $K_S^0K_S^0K_S^0$ and $π^0 π^0 K_S^0$ decays. An updated measurements of the CP-violating charge asymmetries for $B^{\pm}\to η^{'} K^{\pm}$, $ηK^{\pm}$, $ωK^{\pm}$ decays are also presented. The measurements are based on the data sample recorded at the $Υ(4S)$ resonance with $BABAR$ detector at the PEP-II $B$-meson Factory at SLAC. | |
