| Sumario: | A large jet rejection factor for electromagnetic clusters in the high level trigger selection chain can be achieved by using the data from the pixel detectors. This is only a fraction of the total data in the tracker system. A fast algorithm has been developed to match the electromagnetic clusters to the hits in the pixel layers, and it has been shown that a jet rejection factor of 20 can be achieved with an electron efficiency of 96%. |
