D0的B_s振荡和CP破坏的测量

Measurement of B_s Oscillations and CP Violation Results from D0

John Ellison

摘要:

我们提出了一个测量的$B_s^0 - \bar B_s^0$振荡频率,$Δm_s$,使用组合的半轻子和强子$B_s$衰变候选人从D0实验收集的数据在费米实验室Tevatron。我们还提出了几个结果CP破坏,包括改进的测量$B_s$ CP违反阶段的味道标记分析的$B_s^0 \to J/ψ+ ϕ$衰变。

英文摘要:

We present a measurement of the $B_s^0 - \bar B_s^0$ oscillation frequency, $Δm_s$, 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 $B_s^0 \to J/ψ+ ϕ$ decays.
