Abstract
We present a preliminary study of a new technique for measuring Bs0 mixing and CP violation using the decay Bs0→J/ψϕ, ϕ→K+K-, J/ψ→µ+µ-. This technique utilizes the unequal lifetimes of the Bs0 CP even and odd eigenstates, and an angular variable decomposition of the CP content of the final state. This study is based on CDF Run-I observations and Run-II projections, and predicts that the Bs0 mixing parameter xs can be measured with high accuracy in untagged samples if this approach is adopted. A large CP asymmetry may also be possible to measure. The accuracy of this method is shown to increase for higher values of xs as the lifetime splitting of the CP eigenstates increases. The measurement of xs does not depend on tagging, whereas the observation of a CP-violating asymmetry does.
