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