Description
Understanding the matter–antimatter asymmetry of the universe requires precise measurements of CP violation in rare B meson decays. Penguin-dominated decays, proceeding through quantum loop diagrams, are uniquely sensitive to potential New Physics that could modify the expected CP asymmetry. We present a study of B⁰ → ωK⁰_s at Belle II, establishing a full analysis framework using Monte Carlo simulation. Our sensitivity projections show ~3.8σ evidence for mixing-induced CP violation with significantly improved precision over previous experiments. Results on real data are forthcoming.
