Tracking and vertexing in LHCb

The LHCb detector is a multipurpose single-arm forward spectrometer. The main goal of its design is heavy flavor physics, covering broad range of topics such as rare beauty and charm decays, CP violation and dark matter searches. The LHCb tracking system consist of the VErtex LOcator (VELO), the Trigger Tracker (TT), three Tracking Stations (T-Stations) and in the most upstream region, five rectangular muon stations (MUON). This design is very heterogeneous and requires a complex system of charged particle reconstruction algorithms. LHCb has developed a real-time fully automated alignment and calibration system to ensure offline reconstruction quality already at the online level.LHCb's unique trigger setup allows prompt access to calibration and data samples. Such robust techniques with fast accessibility to data does not only directly impact the quality of the LHCb results, but also serve as a basis for the upcoming upgrade.
