Abstract :
A fast track reconstruction algorithm for the ATLAS second level trigger is presented. The timing performance (3.5 ms for a jet reconstruction at low luminosity) is satisfactory; the transverse impact parameter resolution (75 μm) is sufficient to perform an on-line b-tagging, and the full three-dimensional reconstruction produces good seeds for more sophisticated track searches.
