DESCRIPTION:Speakers: Darin Acosta (Univ. of Florida\, United States)\nThe
  trigger systems of the LHC detectors play a crucial role in determining t
 he physics capabilities of the experiments. A reduction of several orders 
 of magnitude of the event rate is needed to reach values compatible with d
 etector readout\, offline storage and analysis capability. The CMS experim
 ent has been designed with a two-level trigger system: the Level-1 Trigger
  (L1T)\, implemented on custom-designed electronics\, and the High Level T
 rigger (HLT)\, a streamlined version of the CMS offline reconstruction sof
 tware running on a computer farm. Both systems need to provide an efficien
 t and fast selection of events\, to keep the average write-out rate below 
 450Hz. For Run II\, the doubling of both the center of mass energy to 13 T
 eV and the collision rate to 40 MHz\, will imply increased cross sections 
 and out-of-time pile-up. We will present the improvements brought to both 
 L1T and HLT strategies to meet those new challenges.\n\nhttps://indico.ifi
