Performance of the LHCb Track Reconstruction Software

Abstract

Abstract The performance of the LHCb track reconstruction software at the time of the DC 06 re-processing is described. For Long Tracks an event weighted efficiency of $91.4~\%$ is found for a ghost rate of $14.6~\%$. For these tracks a momentum resolution of $4.2$ per mille is obtained after a Kalman filter based fit
