\section{Tracking efficiency measurement}\label{sec:trackEff}

The measurement of  track reconstruction efficiency of the \lhcb detector and its reconstruction algorithms efficiency is essential for most analyses carried out by the \lhcb collaboration. Contrary to the other large \lhc experiments, the physics program of \lhcb focuses on relatively low momentum particles. Hence, it is optimized to contain as little material as possible in order to reduce their scattering and hence be able to perform very precise measurements. Therefore, any redundancy in the \lhcb tracking system is removed. The downside of this approach is sensitivity to the performance of tracking detectors and the tracking algorithms. The track reconstruction efficiency is vital for the physics program of \lhcb.
