The LHCb Vertex Detector

LHCb is a forward detector which will study CP violation and other rare phenomena in the decays of Beauty particles at the LHC. One of the challenges of the experiment is to design a fast and efficient trigger for selecting the Beauty events. Apart from providing excellent tracking information for the analysis the Vertex Detector provides one of the most selective triggers in the experiment. The requirements and possible implementation of the Vertex Detector are described.
