使用LHCb测量$Δm_d$、$Δm_s$和$\sin 2 β$

Measurements of $Δm_d$, $Δm_s$, and $\sin 2 β$ with LHCb

Julian Wishahi

摘要:

基于2011年LHCb实验收集的$1.0\,\text{fb}^{-1}$数据,我们测量了$B$介子混合的振荡频率$Δm_d$和$Δm_s$,以及$B^0\to J/ψK_{\text{S}}^0$衰变中随时间变化的CP不对称性.这些测量为Cabibbo-Kobayashi-Maskawa矩阵的酉性测试提供了有价值的输入。

英文摘要:

We present measurements of the oscillation frequencies $Δm_d$ and $Δm_s$ of $B$ meson mixing as well as a measurement of the time-dependent CP-asymmetry in decays of $B^0\to J/ψK_{\text{S}}^0$ based on $1.0\,\text{fb}^{-1}$ of data collected by the LHCb experiment in 2011. These measurements give valuable input to tests of the unitarity of the Cabibbo-Kobayashi-Maskawa matrix.
