B_S Mixing Via Ψ K*, Patricia Mcbride, Sheldon Stone

Physics - All Scholarship

The decay mode Bs à ψ K*is suggested as a very good way to measure the Bs mixing parameter xs. These decays can be gathered using a ψ → ℓ+ℓ− trigger. This final state has a well resolved four track decay vertex, useful for good time resolution and background rejection.
