摘要：
The LHCb experiment is dedicated to the study of the c- and b- decays, including long-lived particles such as K-s and strange baryons (Lambda(0), Xi(-), etc...). These kind of particles are difficult to reconstruct by the LHCb tracking system since they escape detection in the first tracker. A new method to evaluate the performance of the different tracking algorithms for long-lived particles using real data samples has been developed. Special emphasis is laid on particles hitting only part of the tracking system of the new LHCb upgrade detector.
