| Sumario: | This note describes an algorithm for the identification of b-jets at Level 2. The aim of this trigger is to increase the acceptancefor multi b-jets events keeping the same rate as the one given by the present trigger in Et.A simple algorithm based on pixel detector has been shown to achieve rejection factors of about 10-20 for 50% efficiency with processing time well below the LVL2 latency. |
