Measurement of B_s Oscillations and CP Violation Results from D0

Abstract

We present a measurement of the $B_s^0-{\bar{B}}_s^0$ oscillation frequency, $\Delta m_s$, using a combination of semi-leptonic and hadronic $B_s$ decay candidates selected from data collected by the D0 Experiment at the Fermilab Tevatron. We also present several results on CP violation, including an improved measurement of the $B_s$ CP-violating phase from a flavor-tagged analysis of $B_s^0\to J/\psi +\varphi$ decays.
