A Level-1 Tracking Trigger for the CMS upgrade using stacked silicon strip detectors and advanced pattern technologies

摘要: Experience at high luminosity hadrons collider experiments shows that tracking information enhances the trigger rejection capabilities while retaining efficiency for interesting physics events. The design of a based High Luminosity LHC (HL-LHC) is an extremely challenging task, and requires identification high-momentum particle tracks as part Level 1 Trigger. Simulation studies show this can be achieved by correlating hits on two closely spaced silicon strip sensors, reconstructing L1 employing Associative Memory approach. progresses development micro-strip stacked prototype modules performance few detectors will presented. Preliminary results simulated tracker layout equipped with are discussed in terms pT resolution triggering capabilities. Finally, discussion architecture given.
