Measurement of $\Delta m_d$ in $B^0 \rightarrow D^-(K^+\pi^-\pi^-)\pi^+$
We measure the $B^0-\overline{B^0}$ mixing frequency $\Delta m_d$ using $\sim$ 6000 $B^0~\rightarrow~D^-(K^+\pi^-\pi^-)\pi^+$ candidates from 36 pb$^{-1}$ of data taken in physics runs of the LHCb experiment in 2010. We use opposite and same side tagging algorithms which were optimized and calibrate...
