DESCRIPTION:Speakers: GILMORE\, Jason (Texas A & M University (US))\nAddre
 ssing challenges of triggering in the High Luminosity LHC environment requ
 ire development of fast and efficient track-based triggering methods. We c
 onsider a dedicated electronics-based system\, which could be used as a co
 -processor performing fast tracking using data from the pixel detector for
  events passing the CMS Level-1 trigger. In this scenario\, a list of trac
 ks above a certain threshold will be made available for use at the very ea
 rly stages of the software-based CMS High Level trigger allowing fast and 
 efficient reduction in the rate of events necessary to allow performing mo
 re complex and time-consuming reconstruction methods on surviving events. 
 While primarily targeted for later stages of “Phase I” upgrades\, the 
 same system can be utilized in the Phase II luminosity regime as part of t
 he Level-1 trigger logic. In this case\, the system will take advantage of
  the increased Level-1 trigger latency to perform tracking in regions of i
 nterest identified by the Level-1 calorimeter or muon triggers. In this sc
 enario\, the system will either confirm or deny presence of an energetic t
 rack and relay that information back to the Level-1 trigger decision logic
  before the final Level-1 decision to accept or reject an event is made.\n
