Abstract

Description

In this report, we present a preliminary measurement of the Bs0 mixing parameter using samples of four partially reconstructed semileptonic Bs0 decays and one fully reconstructed hadronic decay mode, corresponding to approximately 2.4 fb^{-1} of integrated luminosity. We perform an unbinned likelihood fit to the proper decay length and obtain Dms = 18.53 +- 0.93 (stat.) +- 0.30 (syst) ps^{-1}$.
