Track Reconstruction with the CMS Tracking Detector

Jean-Roch VLIMANT, UCSB

For the CMS collaboration

CMS tracking system

All silicon. 13-16 layers crossed inside-out

Pixels and strips and stereo strips

40% of 3D measurement points

Alignment at 5 m to 20 m uncertainty

Single point resolution from 8 m to 64 m

Few but precise measurement points

CMS tracking performance

Pixels for fast track/vertex reconstruction (online) and very efficient trajectory seeding (offline)

Strips for efficient pattern recognition

Momentum resolution at the percent level

Dedicated track reconstruction algorithms

Tracker and muon system combined
