The CDF silicon vertex tracker: Online precision tracking of the CDF silicon vertex

The Silicon Vertex Tracker is the CDF online tracker which will re- construct 2D tracks using hit positions measured by the Silicon Vertex Detector and Central Outer Chamber tracks found by the eXtremely Fast Tracker. The precision measurement of the track impact parameter will allow triggering on events contain- ing B hadrons. This will allow the investigation of several important problems in B physics, like CP violation and B_s mixing, and to search for new heavy particles decaying to b{anti b}
