摘要：

The LHCb experiment is designed to perform high-precision measurements of CP-violation and rare decays of B hadrons at the Large Hadron Collider. The Silicon Tracker (ST) is a silicon strip detector intended to precisely measure the particle trajectories produced by proton-proton interactions. It has a total sensitive area of about 12 m(2) around the beam axis. The Silicon Tracker has a single hit resolution better than 60 mu m that put strict constrains on its alignment. The current alignment procedure is demonstrated to be fast, robust and able to achieve a suitable alignment precision. Two novelties have been added to the method to improve significantly the alignment accuracy using tracks from vertex-and mass-constrained resonances and as well as track extrapolation with magnet off data. Selected results demonstrating alignment improvements are presented.
