| Abstract: | At the Large Hadron Collider at CERN the proton bunches cross at a rate of 40 MHz. At the Compact Muon Solenoid experiment
the original collision rate is reduced by a factor of
(1000) using a Level-1 hardware trigger. A subsequent factor of
(1000) data reduction is obtained by a software-implemented high level trigger (HLT) selection that is executed on a multi-processor
farm. In this review we present in detail prototype CMS HLT physics selection algorithms, expected trigger rates and trigger
performance in terms of both physics efficiency and timing.
