CMS TriDAS project: Technical Design Report, Volume 1: The Trigger Systems

The trigger is the start of the physics event selection process. A decision to retain an event for further consideration has to be made every 25 ns. This decision is based on the event's suitability for inclusion in one of the various data sets to be used for analysis. The data sets to be taken are determined by CMS physics priorities as a whole. These data sets include di-lepton and multi- lepton data sets for top and higgs searches, lepton plus jet data sets for top physics, and inclusive electron data sets for calorimeter calibrations. In addition, other samples are necessary for measuring efficiencies in event selection and studying backgrounds. The trigger has to select these samples in real time along with the main data samples. This document describes the CMS L1 trigger system. The CMS HLT and DAQ system will be described in the CMS DAQ Technical Design Report scheduled for release at the end of 2001.
