How to produce track parameter resolutions (d_{0}, z_{0}, pt)

Efficiency of track reconstruction depends on the theta angle(angle between projection of momentum on z axis and momentum) and transverse momentum. You can see below dependence on theta for SiD_o1_v03 version of detector model. As you have noticed efficiency of reconstruction falls significantly after 40 due, to the problems with Forward Tracking Disks (after 120^{0} ) and Endcaps(both Tracker and Vertex) (< 40^{0} ).

  D0_resolution can be produced by running following script D0_resolution_angle.cxx:

On the figure below you can see Transverse momentum resolution obtained in the new framework and comparison with Detailed Baseline Design report from 2012(following figure) * This is Pt resolution obtained with SiD_o1_v03 model using momentumres_angle.cxx script:

Pattern recognition

Pattern recognition is a field of applied mathematics, which aim is the classification of objects. For instance, position measurements along particle trajectories can be classified as different physical objects. Please refer to the report that will be attached later on for more details on it.
