$B_s$ Mixing via $\psi K^*$

High Energy Physics - Experiment 2008-11-26 v1

Abstract

The decay mode BsψKB_s\to\psi \overline{K}^* is suggested as a very good way to measure the BsB_s mixing parameter xsx_s. These decays can be gathered using a ψ+\psi\to\ell^+\ell^- trigger. This final state has a well resolved four track decay vertex, useful for good time resolution and background rejection.
